Question

Is the function tan t positive or negative in Quadrant IV?

Answer 1

Well, to answer that question, why not take some values of theta in that quadrant?

Answer 2

Do you know the status of sin t and cos t in Quadrant IV?

Answer 3

I don't know if I'm correct, but...

tan=y/x
sin=y
cos=x

I used All Students Take Calculus.
Which means that in Quadrant IV, only Calculus (cos) is the positive, meaning in Quadrant IV, tan t is negative.

Answer 4

Correct, tan t is negative in Quadrant IV.
