This is the given data table
--------Jan----Feb----Mar---Apr----May----Jun----July----Aug----Sept----Otc----Nov----Dec
Maximum:33.2--32.2--31.2--28.9----25.4----22.2--21.9----23.9----27---- 29.8----31.7----32.9
This is a temperature table and i need to find its sine equation.b3/
y= AsinB(x-C) +D
A=(max-min)/2=(33.2-21.9)/2=5.65
The period is 12 months, so 2pi/B=12 => B= pi/6
D=(max+ min)/2= (33.2+21.9)/2=27.55
C is the half way from the first minimum to the next maximum:
Min: July / 7 Max: January / 13
C=(max+ min)/2=(13 + 7)/2=10
So the equation is: y=5.65sin((pi/6) (x-10))+27.55Well, I want to ask did i do anything wrong?
How to improve this equation to fit the numbers better because the numbers weren't fitted on my graph.
THanks
