(sec 17° / cosec 73°) + (tan 68° / cot 22°) + cos² 44° + cos² 46°

Question

KnowledgeBoat · Accepted Answer

We need to find the value of The above equation can be written as, As, cos(90 - θ) = sin θ, cosec(90 - θ) = sec θ, cot(90 - θ) = tan θ and sin²θ + cos²θ = 1. Using in above equation we get, Hence, the value of the expression is 3.
