Question 172758: 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
Can someone please help me with this.
Thanks

And that is all you need to know since:
sin(theta) = y/r
cos(theta) = x/r
tan(theta) = y/x
and you know that csc,sec, and cot are the inverse.

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.
