In Exercises 1 and 2, use a graphing utility to graph y1 and y2 in the same

Question:

In Exercises 1 and 2, use a graphing utility to graph y1 and y2 in the same viewing window. Use the graphs to determine whether y1 = y2. Explain your reasoning.
1. y1 = cos(x + 2), y2 = cos x + cos 2
2. y1 = sin(x + 4), y2 = sin x + sin 4
