This involves integration, partial and ordinary derivatives of analytical expressions.

Do we have a tool that I can use to check my work?

Example: I want to take the fifth derivative of SIN(x)*cos(y) and all partial derivatives, wrt

to X and Y. I want to make sure I did it correctly.

Then I want to evaluate the results between limits also given by algebraic expressions.

Another example; I have three complex analytic expressions in three variables X, Y

and Z,

and I want an analytic solution to X, Y and Z if one exists.
