Easily Check Your Calculus Homework with Web-Based Calculators

[Chunkysalsa]

So unlike most professors I've had my current calc professor assigns problems in the book that don't have the solutions in the back.

In my opinion homework is for practice and its hard to practice something if you don't even know if you got it right.

So currently I'm learning how to find derivatives and I've found a few web based calculators that are helpful to check my work.

Is there any tool I can use to find solutions quickly or better yet a quick technique to check my work.

Check out a calculus book from your library that has a solutions manual.

Work similar problems from your book that do have answers for practice. Or get a Schaum's outline.

I guess, I'd just like to be more confident in my answers before I turn them in.

Its amazing how the hardest part of calculus so far is algebra. I wish they gave more complex examples back when they taught the basics in high school.

I'd also like a way to check my answers on a test or something. For some easier functions i could graph it on my calculator a use the derivative to plot the tangent line. Doesn't really work for more complex functions or when using something like implicit differentiation.

Mathematica is the best, in my opinion, if you have it at your school you ought to use that. I think it has an online calculator for derivatives too, I know it has one for integrals.

type in 'derivative of cos(x)^2'

its correct.
but don't rely on it.
first solve, and then check.

i was using it wolfram earlier and its good but it won't work for checking problems using implicit differentiation (or at least i haven't figured out how)

I'll check out mathematica

Yeah, but implicit differentiation just means don't forget that y implicitly depends on x, or vise versa. It's really just a notation issue, not a differentiation issue.
