【實用工具app】Binomial Expander|最夯免費app-gigacircle

This is a relatively simple and easy-to-use binomial expander for the iPhone, that does NOT need an internet connection to work! The app takes in an (x + y)^n (where n is a positive number, and x and y are any string or variable with a coefficient, such as 'x' or '3a') equation and expands it using the Binomial theorem.Great for both Mathematics/Engineering/Sciences students and teachers alike.(See http://en.wikipedia.org/wiki/Binomial_theorem for more information regarding the Binomial Theorem.)
