so f(x) = 2sin(t)cos(t)

it has odd symertry, -f(x) = f(-x). but i dont know how relevent this is

I presume you know the basic formulas?

The coefficient of "cos(nx)" is

The coefficient of "sin(nx)" is

Because 2sin(t)cos(t) is an odd function, its Fourier series includes only odd terms- that is no cos(nx) term. [itex]a_n= 0[/itex] for all n.
