Question

Solve the equation.
cot 4x = -1

Answer 1

Solve the equation.
cot 4x = -1

taking cot -1 both sides

$cot \: 4x = - 1 \\ \\ {cot}^{ - 1}cot (4x) = {cot}^{ - 1} ( - 1) \\ \\ 4x = {cot}^{ - 1} ( - 1) \\ \\ 4x = {cot}^{ - 1} ( cot \: ( - \frac{\pi}{4} ) )\\ \\ \\ 4x = - \frac{\pi}{4} \\ \\ x = - \frac{\pi}{16}$
