How to enter expressions

For the most part, expressions are entered using standard mathematical notation, with a few caveats:

Details, quirks, and additional information

I also have a page where you can practice differentiation (derivatives).

While I have tried to test this page fairly thoroughly, it may sometimes fail. If you find it is misbehaving for you, please click THIS LINK to send me an email report of the problem.

For "skipped" functions, this page provides a link to where you can see the details of how to find the integral (follow the link, then click "Show steps"). Note that this might fail for some functions, because some of my notation is tricky to translate to a form that WolframAlpha will understand.

To check if your answer is correct, the computer finds the exact derivative of your function, and compares it to the original function you were asked to antidifferentiate. If those functions have the same output value at 5 randomly selected x values between –8 and +8, your answer is judged to be correct. That should be nearly foolproof, but I have not tested this page to the point that I can guarantee it. (In fact, I know that it fails in a few cases, because of an imperfect simplification algorithm [which I am still working on].)
