Question

If secx = -2, then in which quadrants do the solutions lie?

Answer 1

ANSWER

2nd and 3rd quadrant.

EXPLANATION

The given trigonometric equation is:

$\sec(x) = - 2$

The secant ratio is negative in the second and third quadrant.

But it is positive in the first and fourth quadrants.

The given secant ratio is negative.

This implies that , the solution to given equation lies in the second and third quadrant.
