GRAPHICS CALCULATOR
Easily plot and analyze math functions
on your iPhone !
fxPad is a powerful calculator that plots curves of mathematical functions and computes the coordinates of their remarkable points, automagically at the touch of a finger on your iPhone, iPod Touch or iPad.
It's a musthave for math students and teachers who need to solve equations or find a function's minimums & maximums.
fxPad supports more than 20 classic scientific functions and also allows plotting several curves at the same time, to calculate their intersections instantly.
Unlike other graphing calculators, its amazingly intuitive touch interface makes fxPad productive right from the beginning. If you are proficient with any pocket calculator, you will find that you already know how to use fxPad. No slow learning curve is required ! fxPad will save you $100 compared to the price of a graphing calculator, and takes less space in your bag too!
