Question

Which expression best represents all solutions of x for the equation cot x = –1.25, where k is any integer?

Answer 1

The answer is "
`-0.675+ k \ \pi`"

Explanation:

Given:

`\to \cot \ x = - 1.25\\\\\to \cot \ x = \cot (-0.675)\\\\\to x= k \pi + (-0.675)\\\\\boxed{\boxed{\boxed{x= -0.675 + k \pi}}}`
