Cos theta equals 1/2
WebJun 2, 2016 · As you can see, this is a quadratic equation in cosine. It can be solved by factoring. As you probably know, trinomials of the form y = ax^2 + bx + c, a != 1 can be solved by finding two numbers that multiply to a xx c and that add to b. :. Two numbers that multiply to -2 and that add to -1 are -2 and +1.
