The period is given by - you are given that

"Maximum Value" is a synonym ofamplitudewhich is A in your equation

Now you know A you can find C by subbing in (0,6) for (x,y)

First, it is "pi", not "pie".

The maximum value of y= A sin(Bx+ C)**is**A.

If for some x, Bx+ C= 0, the when (subtract the first equation from the second) . Since we are told that the period is , we can take to get .

Finally, the maximum occurs at . Since we are told that it happens when x= 0, we must have .
