Question

. If cot(θ)=4/3 , evaluate 1-cos(θ) / 1+ cos(θ) *​

Answer 1

Answer:

1/9

Step-by-step explanation:

as we know tan(37°)=3/4

so, cot( theta)=4/3 means 1/tan(theta)=4/3

that means theta=37°

and 3-4-5 is a renown Pythagorean triplet.

so, 1- cos(37°)/1+cos(37°)

so, cos37°=4/5

so, 1-4/5 / 1+4/5

=1/5/9/5

so, Our answer becomes 1/9
