Electrical Engineering/Trigonometric identities in Excel Application.


Dear Prof Cleggsan

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,
Prashant S Akerkar


Here is a list of all functions supported by excel:

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