【實用教育app】Mathhelper|最夯免費app-綠色工廠好玩App

Hello everyone, this is my first application for the Iphone/Ipod Touch App Store called Mathhelper!This app contains several things:-A list of some important and basic mathematical formulas (calculate area, circumference, volume of objects etc).-A list of constants in the mathematics (pi, Euler's number, golden ratio, plastic number and many many more) with detailed information.-Lessons (primitives, derivative, working with fractions, logarithms, basic mathematical rules and more).-Calculators (prime number checker, greatest common divider, quadratic equation solver, random number generator and more).What makes this app different from the other App Store apps? The fact that it contains everything in one single application: formulas, constants, lessons, rules and helpful calculators! All these features for the low price of $0.99 or €0.79!Currently I'm working on more calculators, formulas and lessons as you can read in the app itself!
