In Example 4, change cos 1/2x to sin 1/2x and on the right of the equal sign

Question:

In Example 4, change cos 1/2x to sin 1/2x and on the right of the equal sign change the + to −.

Data from Example 4

Solve the equation cos(x/2) = 1 + cos x (0 ≤ x < 2π).

By using the half-angle formula for cos (x/2) and then squaring both sides of the resulting equation, this equation can be solved:
