Question

cosec^2 60° sin^2 60° -sec^2 60°​

Answer 1

Answer:

I am assuming the question is

Cosec^2 60° × Sin^2 60° - sec^2 60°

We know that sin(x) = 1/cosec (X)

and sec60° = 2

i'e. cosec^2 60° × sin^2 60° - sec^2 60 °

= 1/ sin^2 60° × sin^2 60° - (2)^2

= 1 - 4 = -3

therefore answer is(-3)
