Hi,
i have the following problem, that i can't seem to figure out. I have terms of the type:

(1/(4 g i))Sqrt[3] E^(-I phi)
Cos[theta/2]^2 Sin[psi/2]^3 Sin[theta/
2] (-12 (-1 + E^(2 I phi)) Cos[psi/2] -
4 (-1 + E^(2 I phi)) Cos[(3 psi)/2] +
I Sin[psi/
2] (-E^(I phi) Sin[2 psi - (3 theta)/2] -
4 I (-1 + E^(2 I phi)) Sin[psi - theta] -
E^(I phi) Sin[2 psi - theta/2] + 14 E^(I phi) Sin[theta/2] -
2 E^(I phi) Sin[(3 theta)/2] + 4 I Sin[psi + theta] -
4 I E^(2 I phi) Sin[psi + theta] +
E^(I phi) Sin[1/2 (4 psi + theta)] +
E^(I phi) Sin[2 psi + (3 theta)/2]))

and i would like factor out everything, that is independent of theta, to obtain something of the form:

X[psi,phi]*(a*Sin[theta]+b*Cos[theta]+c*Sin[3*theta/8]+...)

How could this be done?

Thanks in advance
Pascal
