# How do you find the values of the six trigonometric functions given cottheta is undefined and pi/2<=theta<=(3pi)/2?

cot t is undefined when $t = \pi$
$\cos t = \cos \pi = - 1$
$\sin t = \sin \pi = 0$
$\tan t = \tan \pi = 0$
$\sec t = \frac{1}{\cos} = \frac{1}{-} 1 = - 1$
$\csc t = \frac{1}{\sin} = \frac{1}{0} =$ undefined
