Question

if tanӨ = cotӨ, find the value of sin2Ө​

Answer 1

Step-by-step explanation:

Sin 2 × 45

So 1 is the answer

Answer 2

Answer:

From the question we get tanθ = 1/tanθ.

tanθ × tanθ = 1.

tan²θ = 1

tanθ = 1

so θ = 45 degrees.

sin2θ = 2sinθcosθ = 2×sin45 × cos45

= 2 × (1/√2) × (1/√2)

= 2 × (1/2) = 1

so , sin2θ = 1
