Question

√3 tan = 3 sin find the value of sin2 - cos1

Answer 1

Given : √3 tan ∅ = 3 sin ∅

→ tan ∅ = 3/√3 sin ∅

→ tan ∅ = 3√3/3 sin ∅

→ tan ∅ = √3 sin ∅

→ sin ∅/cos ∅ = √3 sin ∅

→ √3 cos ∅ = 0

→ cos ∅ = 0

→ cos 90° = 0

Hence, ∅ = 90°

→ 2 sin ∅ - cos ∅

→ 2 sin 90° - cos 90°

→ 2 × 1 - 0

→ 2

Answer : 2
