Prove the following results: Solve the following:
cos^-1x+sin^-1x/1-π/6=0

Given:-

Take

⇒

We know that, Formula

Thus,

⇒

We know that, Formula

Thus,

⇒

⇒ x = ±1

Prove the following results:

Prove the following results: Solve the following:

sin^-1xsin^-12x= π/3

If cos^–1 x/2 + cos^–1y/3 = a, then prove that 9x²–12xy cos a + 4y² = 36 sin² a.

Solve the equation: cos^–1 a/x–cos^–1 b/x =cos^–1 1/a

Prove the following results: Solve the following:cos-1x+sin-1x/1-π/6=0
