You can put this solution on YOUR website! a function value & quadrant are given. find the other 5 function values
cot= -5, quad=II
find sin, cos, tan, csc, & sec
------
cot = x/y ; So x = -5 and y = 1
----
Then r = sqrt[25+1] = sqrt(26)
-------
sin = y/r = 1/sqrt(26)
cos = x/r = -5/sqrt(26)
tan = y/x = -1/5
---------
csc = r/y = sqrt(26)
sec = r/x = -sqrt(26)/5
cot = x/y = -5
