You shouldn't need a calculator for most calculus. If your answer isn't 1 or 0 and doesn't have a pi term in it then you did something wrong.

Having a calculator for calculus is more of a luxury OP, if you are confused on a definite integral, you can check it and with a TI 83 or 84 or any other for sure. But in general, the shit isnt that hard to do by hand. The only problems that will take more than a page to compute are differential equations and proofs. Your babby's calc 3 will be muh vector fields and equations and double integrals until you get to green's and stoke's theorems

OP that class doesnt require a calculator, you will at worst have some elementary matrix operations to do, and only for taking gradients and partial fraction decomposing.
