You can put this solution on YOUR website! How do i find the 6 trig functions of -7pi/2
-------------
You don't need to list the 6 functions, we know what they are.
"Please help me" doesn't usually attract attention, either, it irritates some tutors so they ignore the problem.
-------
Get the reference angle by add 2pi until the result is positive.
-7pi/2 + 2pi = -3pi/2
-3pi/2 + 2pi = pi/2
--------
sin = 1
cos = 0
tan = sin/cos = undefined
cot = cos/sin = 0
sec = 1/cos = undefined
csc = 1/sin = 1
You can put this solution on YOUR website! is telling you to rotate around the unit circle times in the clockwise direction in increments of .
You know that if you rotate by 4 times, you will come
back to where you started. That leaves that you
have to rotate in the clockwise direction.
The rotating arrow is now pointing in the positive vertical
direction. This is the same angle as , so
