I was just wondering how could one find the solution of equations involving trigonometric and polynomial expressions.
For example, how could we solve$\displaystyle x - cosx=0$?

I can proof that a unique solution exists.Originally Posted by malaygoel
You can approximate solutios with "Newton-Raphson Alogorthm".
I would not be supprised that the solution is transcendental
Most solutions to mixed algebraic/tanscendetal equations are doOriginally Posted by malaygoel
not have simple closed forms in terms of the usual elementary functions
(no don't ask me to prove it). So do however have such solutions, see
