Question

Cot[π/2-theta] =3 then find the value of Cos theta

Answer 1

Answer:

Step-by-step explanation:

Cot ( $\pi$/2 - θ) =3

tan θ = 3

the above equation, we can write-

tan θ = 3/1

by using pyathagores theorem-

AB = 1, BC = 3, AC = $\sqrt{10}$

then we can find-

cos θ = $\frac{1}{\sqrt{10} }$
