Question

question 19 of 30
on a unit circle, the terminal point of θ is (0, - 1). what is tan θ?
a. 0
b. 1
c. undefined
d. - 1

Explanation:

Step1: Identify coordinates

Terminal point is $(0, -1)$, so $x=0$, $y=-1$.

Step2: Use tangent formula

$\tan\theta = \frac{y}{x} = \frac{-1}{0}$

Step3: Evaluate division by zero

Division by zero is undefined.

Answer:

C. Undefined
