Answer:

Undefined


\tan \theta=\text{ undefined}

Step-by-step explanation:

Given that the terminal point on a unit circle is at;


(0,-1)

Recall that from trigonometry tangent is;


\tan \theta=(opposite)/(adjacent)=(y)/(x)=(-1)/(0)

and we know that any number divided by zero is undefined.

Therefore;


\tan \theta=\text{ undefined}

tan theta = undefined
