cot (Theta)= -(Radical 3/1)in quadrant IV.

I got 240 degrees but i dont know how to do the diagram since 240 degrees is in quadrant III. How do you put this in a diagram?

**bobpursley**, Tuesday, May 10, 2011 at 4:28pmoops. It is ctn. I read it as cosine. Duh.

OK, ctn Theta= -sqrt3

or TanTheta=-1/sqrt3

but drawing a small triangle, that means the hypotenuse is 2, and cosine= sqr3 / 2, sin theta= -1/2 Well, I recognize sin=-1/2 as - 30 deg, so the quadrant IV angle then is 330.
