Description

DiffIt! Free calculates and explains derivatives of mathematical functions.

Type in a mathematical function and DiffIt! Free will differentiate it. What's more it can even tell you how it arrived at the result. The explanation traces all the steps and also tells you which rules have been applied.

This easy to use tool can help you learn how to find derivatives of most common functions.

Functions supported are:

sqrt exp

sin cos tan

asin acos atan

sec cosec cot

sinh cosh tanh

asinh acosh atanh

sech csch coth

ln log log2

erf erfc

DiffIt! Free is ad supported. If you like this app and you want to get rid of the advertising, please support us and purchase the full version called DiffIt!

Changes in version 1.1.4

- fixed empty input bug

- fixed parsing bug; invalid expressions are detected more reliably

- modified parsing rules; sin(x)^2 will now be interpreted as (sin(x))^2

Note that sin x^2 is now also interpreted as (sin(x))^2, you need to write sin(x^2) for alternative interpretation.

Changes in version 1.1.3

- improved button design

- back button and Action Bar works according to guidelines

Changes in version 1.1.1

- Fixed linkage error

Changes in version 1.1.0

- Improved parsing "sin x" is now an acceptable abbreviation of "sin(x)"

- Added help text and complete a reference of differentiation rules

- Fixed welcome dialog bug

- Improved expression simplification

Listen Read Device Only Added Installed Free version with ads: The best graphing and scientific calculator here.

As a scientific calculator cFunction supports functions like pow, square roots, trigonometric functions and the logarithm. As mathematical constants, the Euler number e and Pi (π) are supported

On top of that with this graphing calculator you can plot (multiple) functions, calculate derivatives, roots, extrema (maxima or minima of a function), inflection points, value table, certain values, definite integrals, intersections of functions and it can convert between degrees and radian.

The calculator supports the trigonometric functions sine, cosine, tangent,

their hyperbolic representations hyperbolic sine, hyperbolic cosine and hyperbolic tangent

and the inverse trigonometric functions sin^−1(x), cos^-1(x), tan^-1(x), coth, cot, acot.

Using the calculator you can analyze functions fast and simple so it's perfect for your math classes.

Supports english, german, french and spanish.
