Question

use the half-angle formula to evaluate tan(17pi/12

Answer 1

Do you know the half angle formula for tan?

Answer 2

no

Answer 3

\[\tan \frac{ \theta }{ 2 }=\frac{ \tan \theta }{ 1+\sqrt{1+ \tan^2 \theta} }\]

Answer 4

In your equation,\[\frac{ \theta }{ 2 }=\frac{ 17\pi }{ 12 }\] so solve for Θ
