cos (θ) = \frac{- 3}{2}

$\cos (θ) = \frac{- 3}{2}$

Step 1

Move the negative in front of the fraction.

cos (θ) = - \frac{3}{2}

$\cos (θ) = - \frac{3}{2}$

Step 2

The range of cosine is

- 1 \leq y \leq 1

$- 1 \leq y \leq 1$ . Since

- \frac{3}{2}

$- \frac{3}{2}$ does not fall in this range, there is no solution.
