# How do you graph y=cosx+x?

Jan 25, 2017

The graph is inserted. Also see the superimposed graphs of y = x and y = cos cos that are compounded into the graph for y = x + cos x.u

#### Explanation:

The graph is non-periodic. Yet, it is periodic with period (2pi),

referred to the line y = x as the transformed x-axis.

graph{x+cosx [-40.8, 40.84, -20.4, 20.4]}

graph{(y-x)(y-cos x)(y-x-cos x)=0 [-10.2, 10.21, -5.1, 5.1]}
