You can put this solution on YOUR website! Find the exact value in simplest radical form, of all six trigonometric functions given the point: (6,-4)
-------
x = 6 and y = -4
So, r = sqrt[6^2+4^2] = sqrt[36+16] = sqrt(52) = 2sqrt(13)
-------
sin = y/r = -4/sqrt(52) = -2/sqrt(13)
cos = x/4 = 6/sqrt(52) = 3/sqrt(13)
tan = y/x = -4/6 = -2/3
-------------
csc,sec, and tan are the inverse of sin, cos, and cot
