You can put this solution on YOUR website! The terminal side of theta, an angle in standard position, is in Quadrant II and lies on the line y=-8x. What are the six trig functions for this line?
-----------------------
Point on the line: (-1,8)
----
You have x = -1 and y = 8
Find "r":
r^2 = (-1)^2+8^2
r^2 = 65
r = sqrt(65)
==================
sin = y/r = 8/sqrt(65)
cos = -1/sqrt(65)
tan = y/x = -8
----
csc = r/y = sqrt(65)/8
sec = r/x = -sqrt(65)
ctn = x/y = -1/8
================
