Graphs of Sine and Cosine Functions Question? (4.5 / 73)?

Question

Graph f, g, and h in the same rectangular coordinate system for
0 < or equal than x < or equal than 2π. Obtain the graph of h by adding or substracting the corresponding y-coordinates on the graphs of f and g.

f(x) = sin x, g(x) = cos2x, h(x) = (f-g)(x)

I need help with this problem. Correct answer gets 10 points.

Answer 1

I recommend you to draw functions on line by this tool:
