Question

If sinθ – cosθ = 0, find cotθ ?​

Answer 1

Answer:

ANSWER IS 1/4

Explanation:

sinθ - cosθ = 0

⇒ sinθ = cosθ

∴ θ = 45°

⇒ (sin6θ + cos6θ) = (sin45°)6 + (cos45°)6 = (1/√2)6 + (1/√2)6 = 1/8 + 1/8 = 1/4

Answer 2

Explanation:

sinθ - cosθ = 0

sinθ = cosθ

Divide both sides by sinθ

(sinθ) / (sinθ) = (cosθ) / (sinθ)

1  = cotθ

Hence cotθ = 1
