Answer:

b. cosine t less than 0 and cotangent t greater than 0

Step-by-step explanation:

We have the following relation

\frac{\pi }{2} < t

if we apply the cosine function in the relation we get:

cos\frac{\pi }{2}

-1

the cosine of t is between 0 and -1 then (cosine t less than 0)

If we now apply cotangent function in the relation:

cotan\frac{\pi }{2}

0

This means that cotang is greater than 0, therefore the correct answer is b. cosine t less than 0 and cotangent t greater than 0
