HELP needed...

Hello everybody!
Ive got a little problem:
I want to approximate the following function f1 by another function f2.

f1(x)= ( ((1 + 2*sqrt(3)) * tan(x) +

tan(abs(x))*sqrt(1 + sqrt(3) - 3*(tan(x)^2) - 3*(sqrt(3))*(tan(x)^2)) /

(1 + (sqrt(3) * (tan(x)^2))) ) + 1

f2(x)= a + b*cos(x) + c*sin(x)

where x is between -30 degrees and +30 degrees and a,b,c are real numbers.
The problem is to find numbers a,b,c so that f2 approximates f1 best.
Thanks in advance,
