Question 811999: My question: "Determine the equation of a sinusoidal function with period 4, amplitude 2.5, and equation of axis y = –2.5."
I know this question is really easy, I am just wondering if I did it correctly.
y = Asin(B(x - C)) + D
2π/B = 4
2π/4 = B
B =1.57
A=2.5
B=1.57
C=0
D=-2.5
f(x)=2.5sin(1.57(x))-2.5
Is that correct?

=====================
It's correct.
I would use f(x)=2.5sin(pi*x/2)-2.5 instead of 1.57.
