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,
Felix
