Question

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

A. I, II
B. I, III
C. II, III
D. III, IV

Answer 1

C. II, III

Step-by-step explanation

The secant ratio is negative in the second and third quadrants but positive in the first and fourth quadrants.

The given secant ratio is

`\sec(x) = - 2 = - (2)/(1)`

Since the secant ratio is negative, its solution must lie in the third and second quadrant.

The correct answer is C
