Question

Find the values of other five trigonometric functions in Exercises 1 to 5
1
1. cos x=-3- * lies in third quadrant,​

Answer 1

cos x=− 1/2

∴sec x= 1/ cos x =−2

Now

∵sin² x +cos ²x =1

⟹sin ²x = 1 - cos² x ⟹sin ²x =

1-1/4= 3/4

= sin x = ±✓3/2

Since x lies in third quadrant, the value of sinx will be negative.

∴sin x = -✓3/2

csc x= 1/ sin x = -2/✓ 3

tanx= sin x / cos x

= (-✓3/2)/ (-1/2) = ✓3

cot x= 1/ tan x

= 1/✓ 3
