# Thread: Derivative Calculator-Function Calculator-Integral Calculator

1. ## Derivative Calculator-Function Calculator-Integral Calculator

I've put together a calculator that handles polynomial terms with positive powers and no fractions.

Given a polynomial expression, this calculator evaluates the following items:
1) Functions - ƒ(x). Your expression will also be evaluated at a point, i.e., ƒ(1)
2) 1st Derivative - ƒ'(x) The derivative of your expression will also be evaluated at a point, i.e., ƒ'(1)
3) 2nd Derivative - ƒ''(x) The second derivative of your expression will be also evaluated at a point, i.e., ƒ''(1)
4) Integrals - ∫ƒ(x) The integral of your expression will also be evaluated on an interval, i.e., [0,1]

The calculator is located here:

Accepted terms are located on the instructions link. I've also included our automated quiz generator with included answer key software as well.

Let me know if you see errors or want enhancements. Have a great day.

2. The following enhancement to this lesson has been added:

5) Simpson's Composite Rule - ∫ƒ(x) The integral value of your expression will be estimated on an interval, i.e., [0,1] using Simpson's Composite Rule.

I also made my own derivative calculator.
It allows computing the symbolic derivative of functions with one or many variables.
The special thing about it is that the user input is displayed as a graphical formula while typing.
