CPM Homework Help : A2C Problem 10-113

Graph each of the following trig functions:

$y = 2\operatorname{sin}\left(x\right)$ and $y = \operatorname{cos}\left(x\right)$ on the same set of axes.

Hint (a):

Use the input bar below to graph each trig function.

Use your answer to part (a) to graph $y = 2\operatorname{sin}\left(x\right) + \operatorname{cos}\left(x\right)$ .

Hint (b):

Add the corresponding y-coordinates to get the graph of the sum of two functions.

Answer (b):
