$cot 3 θ$ $cot3theta$

Explanation:

Using the identity $cot θ = \frac{cos θ}{sin θ}$ $cottheta = costheta/sintheta$ , we know that $\frac{cos 3 θ}{sin 3 θ}$ $(cos3theta)/(sin3theta)$ = $cot 3 θ$ $cot3theta$

$\frac{cos 3 t}{sin 3 t} = cot (3 t)$ $(cos 3t)/(sin 3t) = cot (3t)$

Trig books give:

$cot 3 t = \frac{3 cot t - {cot}^{3} t}{1 - 3 {cot}^{2} t}$ $cot 3t = (3cot t - cot^3 t)/(1 - 3cot^2 t)$
