# In Exercises 7-10, solve the equation for x. Assume 0 ≤ x ≤ 2 π . cos x = − 1 2

To determine

To calculate: The value of x for the trigonometric equation cosx=12.

Explanation

Given Information:

The provided trigonometric equation is cosx=12.

Calculation:

Consider the trigonometric equation:

cosx=12

Since, Cosine is negative in second and third quadrants. Therefore, there are two solutions for trigonometric equation cosx=12, which can be mathematically determined as:

cosx=12cosx=cos2π3x=<
