Graphing Trigonometric Functions: Sin
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) |
