Finding the angle
Find the angle in Radians...
A circle with a radius of 1.
the point P giving the coordinates (√3/2 , 1/2)
So it rotates through the 1st and 2nd quadrant and ends in the 3rd at point P. The angle in the third I'm unsure of. I know that its already 180 degrees.
would i solve the 3rd quadrant angle by finding it using cos θ A/H
so it would be (√3/2)/1 = 1.225?
Thanks for any help.

$\displaystyle \displaystyle \theta = \frac{7\pi}{6}$
recommend you learn the unit circle ...
