Question
Dear Prof Cleggsan

http://en.wikipedia.org/wiki/List_of_trigonometric_identities
http://www.sosmath.com/trig/Trig5/trig5/trig5.html
http://en.wikipedia.org/wiki/Microsoft_Excel


1. Are all Trigonometric identities (functions,formulas etc)  available in Excel application for plotting graphs ?. Examples : Sec, Cosec, Cot, Sin(A+B), Cos(A+B), Tan(A-B), Sin(A-B), Cos(A-B), SIN2A, COS2A etc


2. Similar to Microsoft Excel applications for desktop, laptops machines are there Spreadsheet apps for Smartphones devices which will plot graphs of the above trigonometric identities ?.


Thanks & Regards,

Your second question is handled most effectively by Chrome docs which has all kinds of available apps for smartphones.

Excel spreadsheet for iPhone:
