Question

1. find the general solution of cot 4x=-1 ?​

Answer 1

Answer:

Step-by-step explanation:

Hala 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}
