Question

How do you find the remaining trigonometric ratios if `sectheta= -1.5` and `pi/2 < theta< pi`?

Answer 1

Find 6 trigonometric ratios of sec = -1.5

Explanation:

`cos x = 1/sec x = 1/-1.5 = -0.67 --> x = 131.81` (Q. II)

sin x = sin 131.81 = 0.75

`tan x = sin x/cos x = 0.75/ -0.67 = - 1.20`

cot x = 1/tan x = 1/-1.2 = - 0.83

csc x = 1/ sin x = 1/0.75 = 1.33
