I have problem with this equation:
. . . . .Solve 2cosx - 2sinx + cos2x = 0
I have tried to solve for x but without success, so then I started to randomly type values of x and I found out that it is pi/4 or 45degrees.
But I am wondering if there is a way to solve it using some mathematical relationships or formulas.
Thank you for your time
