In Exercises 79-87, graph each side of the equation in the same viewing rectangle. If the graphs appear to coincide, verify that thee equation is an identity. If the graphs do not appear to coincide, this indicates the equation is not an identity. In these exercises, find a value of x for which both sides are defined but not equal. cos ( x + π 4 ) = cos x + cos π 4
