Dear Richard

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,

To see the math and trig functions available----- with excel open click on the function key, in the insert function box/select a category/ select math and trig. All of the math and trig functions will be listed.

I have not used graph or charting abilities of excel on a smart phone, so I have no knowledge relative to your question, but I would be surprised if the aps did not exist.

Hope this helps a bit
