Most likely you are trying to understand everything about calculus right NOW. That won’t happen unless you’ve already seen a lot of mathematics already. You need to take it again and fucking cheat your way through it. Cheat on every test and cheat every ass ignments. You already have five copies of them all so you won’t need to study at all.

I don't actually do any sort of complex math in my career. It is more of complex problem solving with engineering-related items. I will say though if you are anything but a Civil Engineer (which isn't even a real engineer), calculous will probably be the easiest math class you are going to take. Differential Equations was probably the most annoying one. The lesson here is just cheating your way through calculous will just set you up to fail later.

non rigorous calc 2 in a nutshell:

integral definition:
[eqn]
\boxed{
\int_a^b f(x) dx \equiv \lim_{\Delta x_i \rightarrow 0}\sum_i f(x_i) \Delta x_i
}
[/eqn]
here the interval [math][a,b]\subset\mathbb{R}[/math] is partitioned into [math]N[/math] subintervals with associated sample points [math]x_i[/math] and lengths [math]\Delta x_i[/math] where [math]i \in [1,N] \subset \mathbb{Z}[/math].

Properties (all of these are immediately obvious from the definition):
Linearity
[eqn]
\boxed{
\int_a^b [\alpha f(x) + \beta g(x)] dx = \alpha \int_a^b f(x) dx + \beta \int_a^b g(x) dx
}
[/eqn]
Combining limits of integration
[eqn]
\boxed{
\int_a^c f dx = \int_a^b f dx + \int_b^c f dx
}
[/eqn]
Flipping limits of integration
[eqn]
\boxed{
-\int_a^b f dx = \int_b^a f dx
}
[/eqn]

Fundamental Theorem of Calculus
[eqn]
F(x) = \int_{x_0}^x f(x') dx'
[/eqn]
[eqn]
F(x + \Delta x) - F(x)
= \left[ \int_{x_0}^{x + \Delta x} f dx' \right] - \left[ \int_{x_0}^x f dx' \right]
= \int_x^{x + \Delta x} f dx'
= f(c) \Delta x
[/eqn]
[eqn]
\frac{d F}{d x} = \lim_{\Delta x \rightarrow 0} \frac{F(x + \Delta x) - F(x)}{\Delta x} = f(x)
[/eqn]
[eqn]
\boxed{
f(x) = \frac{d}{dx} \int_{x_0}^x f(x') dx'
}
[/eqn]
[eqn]
\boxed{
\int_a^b f(x) dx = F(b) - F(a)
}
[/eqn]

Integration by Parts
[eqn]
\int_a^b \left[ \frac{d f}{d x} g + f \frac{d g}{d x} \right] dx = \int_a^b \frac{d}{d x} [f g] dx = f g |_{x=a}^b
[/eqn]
[eqn]
\boxed{
\int_a^b f \frac{d g}{d x} dx = f g |_a^b -\int_a^b \frac{d f}{d x} g dx
}
[/eqn]

Integration by Substitution
[eqn]
\int_a^b f(u(x)) \frac{d u}{d x} dx
= \int_a^b \frac{d}{d x} [F(u(x))] dx
= F(u(b)) - F(u(a)) = \int_{u(a)}^{u(b)} f(u) du
[/eqn]

[eqn]
\boxed{
\int_a^b f(u(x)) \frac{d u}{d x} dx = \int_{u(a)}^{u(b)} f(u) du \quad\text{where}\quad u(x),\; du = \frac{d u}{d x} dx
}

for a non-rigorous setting it makes sense to go over taylor series and geometric series, so...

Taylor expansion
suppose you can represent a function as a polynomial, with an offset [math]x_0[/math] thrown in for giggles
[eqn]
f(x) = \sum_{n = 0}^\infty \alpha_n [x - x_0]^n
[/eqn]
[eqn]
f(x_0) = \alpha_0 + \alpha_1 0^1 + \alpha_2 0^2 + \alpha_3 0^3 + \alpha_4 0^4 \dots
[/eqn]
[eqn]
\frac{d f}{d x}(x_0) = \alpha_1 1 + \alpha_2 2 \cdot 0^1 + \alpha_3 3 \cdot 0^2 + \alpha_4 4 \cdot 0^3 \dots
[/eqn]
[eqn]
\frac{d^2 f}{d x^2}(x_0) = \alpha_2 2 \cdot 1 + \alpha_3 3 \cdot 2 \cdot 0^1 + \alpha_4 4 \cdot 3 \cdot 0^2 + \dots
[/eqn]
[eqn]
\boxed{
f(x) = \sum_{n = 0}^\infty \frac{1}{n!} \frac{d^n f}{d x^n} (x_0) [x - x_0]^n
}
[/eqn]

Geometric Series

Usually people are bad at calculus because they suck at algebra and trigonometry. so go over those first and make sure you have a solid foundation for example the reverse quotient rule uses partial fraction decomposition you might of seen in high school. Next do as many practice problems and readings until you feel you feel you have mastered it. Some profs will focus on different things so make sure you are able to read what they prof emphasizes. If you need more help on this ask your classmates they will usually have a clue as to what the prof is emphasizing. Make sure you feel confident enough that your able to walk into the lecture hall and solve any problem the prof shows. If all else fails use professor leonard on youtube. I understand what it feels like to fail a seemingly easy course so stick through it. Sometimes your prof could be absolute ass in which case change profs or hell even switch unis if you can.

I just graduated with my math degree this year and got a first class honours. I didn't fail Calc 2 (i'm assuming this is the same as multivariable calc, ODE's, Series, etc. My country doesn't have 'Calc 2'), but i didn't too well, so keep at it.

The reason i think many find it difficult is because of the number of definitions, equations, and identities you have to memorize is just insane (at least for me), especially the fucking trig ones. In my course they didn't supply a data sheet so you have to memorize it all.

I'm being absolutely honest when i say this - my last two years of my degree were much easier than the 2nd year. Differential and integral analysis were certainly easier imo. But, in my last two years i barely had to memorize anything, mainly just axioms and some definitions, the theorems could be proven as long as you know the axioms and definitions - everything else just flows as you go.

Also, set yourself problem sets in increasing difficulty. Your lecturer will only provide you with easy and mediocre problems. Use textbooks and books for more difficult problems (the ones more likely to come up in the exam).

Assuming you're a burger from the class being called Calc II. I lived in the USA and attempted university there before I quit and came to Europe, and coming from one burgertard to another, I think you're probably lacking the necessary foundation to do well. Higher education in the US has a tendency to throw people in advanced math without caring if they have the necessary pre-requisites. You really need to go back to Algebra, Trigonometry, Calc I, and study them hard. Khan Academy, Algebra for dummies workbook, and Schwam's outline for trig are all helpful resources. Grind old exams and practice problems especially Algebra II concepts as advanced algebra will crop up a lot in Calculus problems. It will take time to master the foundations, so you may want to time off due to the fast paced nature of the semester system. I could barely add fractions or do elementary algebra when I graduated high school in the US and I passed Calculus with an A. You can do it, it just takes time.

How to pass Calc 2: become proficient in integration by trigonometric substitution, integration by partial fraction decomposition, integration by parts, and learn how to recognize types of series, and the various series divergence tests (I think there's around 5 of them). Altogether, that's like 10 things to learn. Can you learn 10 things? Of course, it helps a lot to be good at every calc 1 skill going into it. I studied calc 1 for about 3 months, completely uninterrupted, then studied the aforementioned calc 2 subjects for a month while working a full time job and still managed to pull a B. With more prep time, an A would have been easy.

This is what made me quit my physics degree in second year. I got almost perfect on all the homework assignments (which weren't easy, btw) in E&M. I also got above average on all 3 midterm tests. I was at a point where everyone around me was getting like 40-60% and I was getting in the high 70s on the midterms so going into the final I was pretty strong.

Lo and behold the final was EXTREMELY difficult. I never did get my exam mark (and I do not want to know it), but my final grade in the course was a C. And at my university, they do not even have "minus" letter grades so a C means it was anywhere between 60 and 64%. That is like I didn't even take the final exam. I must have gotten an actual 0 on it, or close.

The reason university profs pull this bullshit is because they need to keep the class average at a certain level to preserve "academic rigor", so if your class is doing too well in a STEM subject, your prof is just going to write an exam that is impossible to do good on to bring everyone's grade down.

I quit because I just do not have the patience or the mental fortitude to have people constantly playing these little games with my emotions. It is no wonder so many university students being claiming mental health issues.

I actually never had trouble with the math. In fact, I only started to struggle a bit with calc 3 when we got to surface integrals and line integrals, and all those wacky rules. I think the reason why that was, was that at that point it was had to ride on intuition anymore and because I was obviously doing the stream of math classes aimed at science majors and engineers I didn't have the mathematical maturity to really understand the proofs... and even for that level in general, the proofs of things like Stokes' theorem, Green's theorem, etc were just handwaved. But overall I got good grades in all my math classes up to quitting.

But you are right, I didn't really enjoy physics the way I thought I would have. And even sitting down and grinding math problems got old after about a year. I really did enjoy it for a pretty long time but when you're doing the same thing every single day nonstop under the threat of falling behind and failing it takes a toll on you and the enjoyment disappears.

Overall, I think the pressure of university sucks the passion right out of you. At least that is true for some people.

People in here bitch about calc but I did well in all my calculus courses. I am doing discrete math right now and it is such a pain. It's boring as fuck, reading the textbook is boring, all the questions are like a fucking story, and the answers are also a story. It's a lot of "translate the logic into english" and if you can't translate English into logic or vice versa properly then you're fucked. And tons and tons of fucking rules you have to memorize and "keep in your back pocket" all the time (ie rules of inference, long table of logical equivalences etc).

I used to love math but this shit is terrible. Holy fuck bring me back to calc and linear algebra, this shit makes me want to blow my brains out.

Why the fuck does a computer science degree require so many math courses? I have to take linear algebra, calculus 1, calculus 2, discrete math, mathematical logic, probability.

Not really. My theory is that there are some people that see all math as esoteric numerology. As a bunch of random rules and statements to memorize and then regurgitate when needed. Those people will fail calc 2 all the time because calc 2 is really the first time that math starts getting dense. If you see the connections, calc 2 is like 3 theorems and then maybe 3 general algorithms for computing integrals and derivatiges. If you don't, calc 2's rules number in the hundreds.

Are we gifted for understanding the connections in math? Not really. I don't consider myself gifted at all. I think that if you just start working under the assumption that math isn't numerology and then ponder the rules for a little bit you'll notice the pattern.

That is a lie. In America, calc 1 is limits, derivatives and applications, the hospital rule, antiderivatives, definition of the definite and indefinite integral, fundamental theory of calculus. Calc 2 is integration techniques, first order differential equations, infinite series, and parametrization. Calc 3 is functions in multiple variables, multiple differentiation, multiple integration, line, surface, and volume integrals. At least this is true for applied/engineering streams. For pure math some universities omit the vector calculus from calc 3 and some calc 2 courses do not introduce differential equations, leaving those topics to be covered in depth in courses of their own.

the only ones of note are the basic definitions, pythagorean identity, law of cosines, and sum/difference identities. all else can be derived from those.

I will paint this on my wall ty. Should be fairly easy to get methylphenidate. Not my first time I kickstart positive habits with stimulants, and it works.

Would you recommend ritalin or concerta?

calc 2 was my favorite math class desu. All the calcs were fun but something about infinite series is really captivating.

I didn't not like calc 2, it's just frustrating that almost none of the stuff I studied (Taylor series and proofs) ended up in the exam

You've studied for 5-8 hrs a day? And still failed this many times? Something is off.

The Textbook has a bunch of literary jargon that is made to be difficult. Don't learn through that.

Just Youtube it man, there's a bunch of videos teaching you via real people speaking plain english.

Also, don't try to 'understand' Calculus, simply learn the calculation processes you need in the course - the "understanding" only clicks later on.

If all else fails, cheat. Universities (especially in the US) are scam places anyway. Don't waste your money

I did. I also felt like I understood more than most. Still failed.

I remember taking Calculus 2 and being so overwhelmed by my other classes, yet very interested in the content of the course.

I've had the chance to work as a calculus tutor for numerous years. I enjoyed how the material gets even more interesting when you're the one teaching it to others.

But I look on the bright side. Understanding most of what I did in the Homeworks and passing calc 1 shows I am not a complete retard.

i mean with that attitude, age means nothing if you have spent 5 years jerking off. idk about your math skills, maybe you don't study the right way, maybe math is not for you, but you shouldn't compare yourself to others.

How many years till graduation by your estimate?
I suggest getting help from peers or seniors, if you spend that much time and still fail then you probably are studying inefficiently

>If you can get away with cheating your way through life, you earned your success.
this is the biggest with current Chinese people, not their race, face or cuisine. This attitude, that me cheating won't hurt me. And as long as it won't hurt me, who am i to care about whether it hurts others.

But it does hurt your future. If the school grades on a curve you hurt your classmates. And you may endanger others with attitude. Plan buildings that collapse, planes that fell off.

Like c'mon you can't be this arrogant. I have plenty friends over there' and they are really cool people! Yes! But please show more care and pride in your work! It shows! I know everyone cheats around you, but that's not a good law to follow. Be straight. Be honest. I know it's hard, because obviously you have good experiences with cheating. Please don't cheat in school. The point of the school is that you can tell your future employer you are dependable and can learn any shit you are given. Not that you will pussy out. Same for work. Please don't cheat on work. If you give quality work, your past business partners will come back, don't just show face, actually provide quality service and care. Be the change.

By never studied do you mean not watching any lectures or reading anything at all throughout the semester.
In my uni we have to deliver some assignments and im just wondering if watching the videos from the related lectures and then doing the assignment counts as studying.
