evaluate. write your answer in simplified, rationalized form. do not round. tan 0° =

Explanation:

Step1: Recall tangent formula

$\tan\theta=\frac{\sin\theta}{\cos\theta}$

Step2: Substitute $\theta = 0^{\circ}$

When $\theta = 0^{\circ}$, $\sin0^{\circ}=0$ and $\cos0^{\circ}=1$. So $\tan0^{\circ}=\frac{\sin0^{\circ}}{\cos0^{\circ}}=\frac{0}{1}$

Answer:

$0$
