Question

The following data represents the normal monthly precipitation for a certain city.
(pic q10 attached)
Draw a scatter diagram of the data for one period. (You do not need to submit the scatter diagram). Find the sinusoidal function of the form (pic q10a) attached that fits the data.

Answer 1

This is a note from my teacher

"The general form of the sine function is:
y = Asin(ωx + Φ) + B
where:
'A' is the amplitude of the function.
The period of the function is: T = 2pi/ω
The phase shift of the function is: Φ/ω

A positive phase shift means the graph has moved to the left, while a negative phase shift means the graph has moved to the right.Use your graph to determine the variables A, Φ, ω and B. You can then write the equation for the graph. Review what each variable stands for. Once you know them all substitute in the general formula. As a note for these trig functions, it is best to leave them in terms of pi where possible. Please refer to section 4-2 for examples and sample problems."
