Use a graphing utility to confirm the solutions found in Example 6 in two different ways.

(a) Graph both sides of the equation and find the x-coordinates of the points at which the graphs intersect.

Left side: y = cos x +1

Right side: y = sin x

(b) Graph the equation y = cos x + 1 − sin x and find the x-intercepts of the graph.

(c) Do both methods produce the same x-values? Which method do you prefer? Explain.
