Question

)a)If cot θ = 1/√3, then find the value of (1- cos2 θ)/(2 - sin2 θ) .​

Answer 1

Answer:

Step-by-step explanation:

given cotA=1/√3

cotA=cot60

A=60

therefore (1- cos²θ)/(2 - sin²θ)

Putting the value of θ we get,

(1-cos²60)/(2-sin²60)

=1-(1/2)²/2-(√3/2)²

=1-1/4/2-3/4

=4-1/4/8-3/4

=3/4/5/4

=3/5
