Solve the following equation:
(0,1)
✓2 Cos x + 1 = 0

The given equation is

We need to determine the solution of the equation.

Solution:

The solution of the equation can be determined by solving the equation for x.

Let us subtract both sides of the equation by 1.

Thus, we get;

Dividing both sides by , we get;

Rationalizing the equation, we have;

Simplifying, we get,

The general solutions for is

Therefore, the solutions of the equation are and
