Explain how to use the figure to solve the equation 2 cos(x) - 1 = 0. y = cos x The equation 2 cos(x) - 1 - 0 is equivalent to the equation cos(x) - . So the intersection points of y = cos(x) and y= represent the solution of the equation 2 cos(x) – 1 = 0. State the solutions of the equation on the interval (-27, 27). (Enter your answers as a comma-separated list.)
