Question

How do you find the value of `tan^-1 sqrt(3)`?

Answer 1

`tan^(-1)(sqrt(3)) = pi/3`

Explanation:

Note `tan^(-1)` is defined as a function with values restricted to the range `[0,pi/2)`
and
if `theta = tan^(-1)(sqrt(3))`
then `tan(theta) = sqrt(3)`

A basic reference triangle looks like:

`theta= 60^@ = pi/3`
