Open a new widow, show the Algebra View and the Graphics View.
1. Begin by creating three sliders: a_1, ω_1, and φ_1
2. Enter the sine function: g(x)= a_1 sin(ω_1 x + φ_1)
3. Create three more sliders: a_1, ω_1, and φ_1
4. Enter another sine function:
h(x)= a_2 sin(ω_2 x + φ_2)
5. Create the sum of both functions:
sum(x) = g(x) + h(x)
