Question

The value of sin^2 60° - 1/cosec^2 30° is​

Answer 1

Answer:

(1/2)² -(1/2)²

= 0

if the answer correct then mark me as brainliest

Answer 2

Answer:

We know that,

sin 60° = √3/2

cosec 45° = √2

cot 30° = √3

tan 45° = 1

Putting these values in the given equation,

⟹ [(3/4) – 2] + [3 + 1] = 11/4
