Joined: Sep 2011 Posts: 2 Thanks: 0  Free Scientific Graphing Calculator for smart phones android I would like to invite you to try our free Graphing Calculator for smart phones android 2.1 and up. Couple months ago, I and my husband (both MD in math) has released its first, newborn version: https://market.android.com/details?i...ndroid&feature It is for free, and we are going to develop it, to adjust it to your needs, and to share it for free at least for couple more years. Now it calculates, builds graphs & function tables (to switch between modes, use a menu). It works with complex numbers (), hyperbolic functions, derivatives. This month, we are going to release its next version with optical character recognition to draw formulas by finger to input. We would be happy if you try our calculator & share any thoughts or recommendations how to make it more convenient for you, what new features would you like to use, because we really want to satisfy you & to make your dreams come true. Have fun playing with my favorite application! MathLab

If you have any questions how to use it or recommendations how to make it more functional, practical, convenient and useful for you, please ask or write your feedback here. Recently, we've changed the description of the calculator a little. Hope, the new description is more clear: 1. Calculator  arithmetic expressions +,,*,/  exponent, square root, logarithms (ln, log)  trigonometric functions sin ?/2, cos 30°, ...  hyperbolic functions sinh, cosh, ... (press and hold "e" key)  inverse functions (press and hold function key)  complex numbers, all functions support complex arguments  derivates sin' x, ... (press and hold ° key) 2. Graphs  multiple functions  scrollable and resizable  function values and slopes 3. Tables  multiple functions  scrollable and resizable  adjustable precision and step Buy the way, look at the picture with a frog below If he had the calculator he would have gotten his meal!

Definetly the app does a lot of calculations and graphic work. Just as mentioned on these posts. It has many options, the one that I best like is about saving functions and variables to use them in the future.
