Question

`cos^(−1)(1/2) + sin^(−1)(1) + tan^(−1) 1/sqrt3` is equal to ______.

विकल्प

• π

• `π/3`

• `(4π)/3`

• `(3π)/4`

Answer 1

`cos^(−1)(1/2) + sin^(−1)(1) + tan^(−1) 1/sqrt3` is equal to π.

Explanation:

`cos^(−1)(1/2) + sin^(−1) (1) + tan^(−1)1/sqrt3`

= `π/3 + π/2 + π/6`

= `(6π)/6`

= π
