Question

If sinθ= cosθ, then find the value of 2tanθ+cos^2θ

Answer 1

Answer:

We have, sinθ= cosθ

So, 2tanθ+cos^2θ=2sinθ/cosθ +cos^2θ=2cosθ/cosθ +cos^2θ=2+cos^2θ ans.

Answer 2

Answer:

Step-by-step explanation:

★ TRIGONOMETRIC REDUCTIONS ★

Given that :

Sin θ = Cos θ

Possible for only one set

θ = π / 4

Now , required value : 2Tanθ + Cos²θ

2 Tan45° + Cos²45°

2 ( 1 ) + 1/2

5/2
