Need Help with Unit Circle

Postby John Q » Thu Oct 06, 2011 11:20 pm

I have: Sin0(slash through 0)= -5/13; 3pi/2<0(slash through0) <2pi

Then what does: sec0=
csc0=
cot0=
cos0=
sin0=
tan0=
(above 0 have slashes through then)

Any help would be greatly appreciated

You've drawn the right triangle in the given quadrant, used the Pythagorean Theorem to find the length of the third side of the triangle, and... then what? Where are you stuck in the process of copying off the numbers?
