We are given the expression cos (2x) = sqrt2/2 and is asked to evaluate the value of x. In this case, we can use a calculator to solve the problem. Using degrees mode, 2x is equal to 45 degrees which means x should be equal to 22.5 degrees. Using radians mode, x is equal to pi/8

Solve this equation:cos (2x) = sqrt2/2

Solve this equation:

cos (2x) = sqrt2/2
