I am actually provided with the function I(x)=I0-I1cos(x-x0) and this function will fit the lowest part of my curve and the program will derive x0 which is the value of x when the y value is the lowest. On the other hand, the function I(x)=I2+I3cos(x-x1) will fit the highest part of the curve and x1 is the value of x when y is the highest.

Can somebody explain those 2 functions and how the software fit the curve with it and how all this can be related to the Taylor's Series?
