Any recommendations on a good calculator for advanced calculus, PDE, DE, linear algebra.

My dad (nearly retired electrical engineer) is giving me this monster.

I have a feeling its going to take as much work as a new university module to figure out how to use it.

I would get a FX115es+ or FX991ex in case of the professor banning graphing calculators as well as never having to worry about the battery dying.

You need a calculator only if your class consists of computing trivialities instead of doing actual problems. This is why in high school trig they teach you like 4 angles and then all problems consist of those 4 angles. Nobody gives a shit about which fucking decimal the answer is, what matters is the deduction process. You should ask your professors why in the fuck they are making you bother with that bullshit.

How about you try calculating the yield stress of an exhaust pipe on a gas/oil fed boiler, with two kinds of burners, optimal air supply conditions, entirely by hand, plus you have 3 other similarly tedious problems to work on and some extra questions to answer in 5 or more sentences.
You have 50 minutes for it.

All of that would be computable by hand given ideal conditions. And then plugging in whatever specifications a real problem requires is a triviality. The real question is why are your professors making you worry about details that in industry computers handle. All you really need is to understand the concepts so that then you know what the computers are doing and can use the tools appropriately.

Unfortunately, I have. I still wonder why some professors do this.

My first guess is that these people are incompetent, and their idea of coming up with a new problem is changing a tiny bit of a well-known problem to turn it into a mess and now that is a "hard" problem.

>>10224620
Ideal conditions in the mathematical sense, brainlet. It's not hard to make the answer of any problem just be some combination of pi, e and the other usual suspects.

Why do you need a calculator? There are websites online that will calculate derivatives, integrals, eigenvalues, groups, matrices, graph functions. Pretty much every computational problem you will see in undergrad there is a website that will solve it online and I didn't even mention matlab. Physical calculators are a thing of the past, something that you only need on tests.
