Could you please show us the graph so we could answer as correct as possible? Thanks!
Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.
Examples: cos(2π),cos(100π),cos(60π)
Let say the number of the months is t, the total amount of depo is a and a0 is the initial amount of money deposited. You can put it like this:
a= f(t) = a0 + x*t
You can solve the equation by inserting two of any t value. If you use f(8)-f(4) it will be
a0+ x(8)= 2500
a0+ x(4)= 1500
___________-
8x- 4x= 1000
4x= 1000
x=250
Then the new equation would be:
a= a0 + 250*t
Putting f(4) value you can find a0
1500= a0+ 250*4
a0=1500-1000=500
The final equation would be
a= 1000+ 250*t
