Question

find the value pls answer fast need help​

Answer 1

Given sin θ = 3/5

In trigonometry,

sin² θ + cos² θ = 1

9/25 + cos² θ = 1

cos² θ = 1 - 9/25 = 16/25

cos θ = 4/5

tan θ = sin θ/cos θ = 3/4.

cot θ = 1/tan θ = 4/3

Now to find

(cos θ - 1/tan θ)/2cot θ

⇒ (4/5 - 4/3)/(8/3)

⇒ (-8/15)/(8/3)

⇒ -1/5

-1/5 is the answer.
