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.
Very useful for math or physics exercices
✓ Compute first and second derivative
✓ Nice looking functions equations
✓ Lot of functions, like abs, sqrt, cbrt, ln, exp, log, and 24 trigonometrics functions (cos, sin, tan, sec, acos...)
✓ No Internet connection needed
✓ Syntaxic coloration (optional)
In this app you should enter NUMBERS, not functions! Also,exponents are already there,after each coefficient,so you should not enter any.
About the app comments:
0, 1, & 2 are not giving any answer,because with these numbers it is not a quadratic equation,it is a linear equation.
It works like this, if you have got an equation:
5x^3 - 7x^2 + 2x + 9 = 0
Then you have to select a Cubic equation,and enter the coeffictients as follows:
You cannot enter any functions, and I don't understand why would you do that,then it stops being a polynomial and this app is a polynomial solver!
If you got any problems with my app,please email me before you give a low score, I am sure that with your help I can fix any problem there is with my app! If you don't email me,I have no way to fix the problem,because I just don't know what the problem is!
Thanks very much for all good comments, that's why I made this app,to help people,thanks for a appreciating it!
This free trial version does not specify the process of calculating the derivative, only the final result is shown.
Try it before purchasing. Update your software application up to the commercial version, with the derivative calculation process shown.
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:
sin cos tan
asin acos atan
sec cosec cot
sinh cosh tanh
asinh acosh atanh
sech csch coth
ln log log2
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
- Crash Fixes
- More intuitive UI
You can also solve differential equations and plot graphs of your choice
Now, do your homework easily when the app :
-- Shows all the steps of differentiation and integration
-- Supports a wide range of functions (trigonometric, polynomial, logarithmic / a combination of them)
-- Draws a graph of any mathematical function
-- Allows you to solve differential equations with initial value problems.
-- Allows you to view the raw data of every computation
-- Has pinch-to-zoom feature so that you can analyze your solutions well
-- Uses multicolored graph plots so that you can compare the solutions of differential equations

Q. Is there are tutorial anywhere explaining how to use the graphing calculator?
A. There are three into tutorials in the app for the calculator, graph equations, and graph screens. Additional tutorials can be found on our website http://www.mathally.com/
Q. How do I get to the keys for pi, e, solve, etc?
A. There are four keyboard pages. Each swipe direction across the keyboard moves you to a different page. The default page is the swipe down page. To get to the page with trig functions, swipe left. To get to the matrix keys, swipe up. To get to the last page, swipe right. No matter what page you are on, the swipe direction to move to a specific page is always the same.
Q. What do you have planned for future releases?
A. You can keep up to date on the latest news on our blog at http://mathally.blogspot.com/ . This news will include what is coming up in future releases. Also feel free to leave comments and let me know what you think!
