Then clearly, x = 30 degrees or pi/6 radians. Now if I differentiate both sides of the equation with respect to x (because both are equal, their derivatives should also be equal), I will have cos x = 0, right? But that means x = 90 degrees, which is obviously not the solution! pioneer town in wimberley https://deeprootsenviro.com
