Question

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

Answer 1

2nd and 3rd quadrant.

Step-by-step 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.
