Find Theta in the degree measure for the indicated quadrant. Show the diagram.
cot (Theta)= (Radical 3/1)in quadrant IV.
I got 240 degrees but i don't know how to do the diagram since 240 degrees is in quadrant III. How do you put this in a diagram?

sqrt 3 is greater than one, how can the Cosine be greater than one?

Do i have to change it from cot to cos?

oops. 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.
