Question

Prove this
I want the explanation of cosec²7π/6
and use superscript!​

Answer 1

Step-by-step explanation:

Given : 2sin²(π/6) + cosec²(7π/6) * cos²(π/3)

=> 2sin²(π/6) + cosec²(π + π/6) * cos²(π/3)  

=> 2sin²(30°) +cosec²(30°) * cos²(30°)

=> 2(1/2)² + cosec²(30°) * cos²(30°)

=> 2 * 1/4 + 4 * 1/4

=> 1/2 + 1

=> 3/2

Hope it helps!
