    Consider the angle \theta = \arccos\left(\frac{-\sqrt{3}}{2}\right)

    Look at the 30-60-90 triangle here Special right triangles - Wikipedia, the free encyclopedia

    Do you notice anything about the side lengths in relation to the problem?

    Now map this onto this circle for where \cos is negative. Have a read of this. http://www.haverford.edu/physics/Mat...Trig_Ident.pdf
