Enter any trig equation and the range and this will calculate the solution. It does just what it says on the tin. So if you have work that you need to check, then look no further.
The tool is taken from the selection of tools that appears on my live worksheet app entitled Trig Identities and Equations, that appears on my developer page.
Hope it proves helpful.
