Find the exact value of each trigonometric function:

1) cot 135 degrees

2) tan -30 degrees

3) cot (-pi)


Show your work.


This is from trigonometry or Algebra 2.

Please don't answer if you don't know it.

Verified Answer :

cot 135 is the same a 1/tan 135, which is equal to 1/-1, so cot 135 is -1

tan -30 is the same as tan 330, which is -\(\sqrt{3 }\) / 3

cot -π = 1 / tan π, which is 1 / 0, and you can't divide by 0, so cot -π is undefined
