This easy to use app calculates the derivative of any formula you enter into it. It will give you both a graphical representation of the derivative, so you can easily understand the output formula, and a representation in text which other software can understand.

No internet connection needed! All calculations are done offline on your device!

This app isn't just a list of derivatives, it uses the quotient rule, product rule and chain rule recursively to produce derivatives.

## MRD Derivatives

Need to take a derivative? Whip it out and put it in! No internet required!

Input the function and the app will tell you the derivative of that function.

e.g. 2x^x+3x^2, sin(x), cos(sin(x)), etc. You get the picture...

Need to take the derivative more than once? Just hit derive again! Or, plug in a value for x and evaluate.

This derivative calculator also solves bounded integrals, numerically. It will factor polynomials for you, and simplify your answer.

Supports all basic calculus functions.

The best part? It actually works! Although, for extremely complicated functions the derivative may not be as simplified as possible (but it will still be correct)

Perfect for on-the-go mathletes.

Takes practically no space.

Note: Parenthesis must match up before you can take the derivative.
