Best curve fit

Hi,

Good morning everyone. I'm a little confused with this one: I have a set of n data points (x and y pairs) for which I want to to do the best fit (by the least squares method maybe) to a function of the type:

Code:
y = a * sin (x) + b * cos(x) + c
Can you please help me define the linear equations for getting a, b and c?

I would apreciate the help, since I have some urgency on this one...

Kind regards

Kepler
