Write an equation of the sine function with:
amplitude = 7
period = 3π
phase shift = π
vertical shift = -7
------------------
Form:: y = a*sin(bx+c)+d
Amplitude:: a = 7
Phase::: (2pi)/b = 3pi implies that b = 2/3
Phase shift:: -c/b = pi implies that c = -(2pi/3)
Horizontal shift:: d = -7
-----
Equation:
y = 7*sin((2/3)x -(2/3)pi)-7
OR
y = 7*sin((2/3)(x-pi))-7
