Question

Prove that sin 37/cos 53 + 1/2(cot 50/tan 40) -1/2 = 1

Answer 1

Answer:

Given that Tan(cos inverse of x ) = sin (cos inverse of 1/2) i.e sin ( cos inverse of 1/2) = sin (sin inverse of pie ‑ 1/2) = pie by 2 Therefore Tan (cos inverse of x) = pie by 2 Cos inverse of x = tan inverse of pie by 2 We know that tan inverse of pie by 2 =0 Therefore cos inverse of x =0 i.e, x=pie by 2 I hope this is helpful
