(sin 35° cos 55° + os 35° sin 55°) / (cosec² 10° - tan² 80°)

Question

KnowledgeBoat · Accepted Answer

We need to find the value of As, sin(90 - θ) = cos θ, cos(90 - θ) = sin θ, tan(90 - θ) = cot θ, sin²θ + cos²θ = 1 and cosec²θ - cot²θ = 1. The above equation can be written as, Hence, the value of the above expression is 1.
