<PRE><B>Question 172758</B>
I have a question that I am not sure if I started right.
Find the exact values of the six trigonometric functions of O(theta) if the terminal sie of O(theta) in standard position contains the point (-5,-4)
I know x=-5 y=-4 and I came up with r=6.4
----------------------
r = sqrt(41) =~6.4
------------
x = -5
y = -4
sin = y/r = -4sqrt(41)/41
cos = x/r = -5sqrt(41)/41
tan = y/x = 0.8
---------
The other 3 are just the inverses.
