I was just wondering how could one find the solution of equations involving trigonometric and polynomial expressions.

For example, how could we solve$\displaystyle x - cosx=0$?

You can approximate solutios with "Newton-Raphson Alogorthm".

I would not be supprised that the solution is transcendental - Jun 19th 2006, 07:52 AMCaptainBlackQuote:

(no don't ask me to prove it). So do however have such solutions, see
