Find the value of `tan15^(@)`

Explanation

To find the value of \( \tan 15^\circ \), we can use the tangent subtraction formula. We can express \( 15^\circ \) as \( 45^\circ - 30^\circ \). The formula for the tangent of a difference is:

\[ \tan(x - y) = \frac{\tan x - \tan y}{1 + \tan x \tan y} \]
