Hi,

I want to find the real and Imaginary part of this equation, without losing the exponential forms. 

(I*(1/2))*(I*R*C*C1*omega__n-L__1*C*exp(I*eta*T[2])*e^2*eta^2*C2-5*L__1*C*exp(I*eta*T[2])*e*eta*omega__n*C2+(3*I)*R__n*C*C1^2*C2*omega__n-3*gamma__1*C*C1^2*omega__n^2*C2-13*L__1*C*exp(I*eta*T[2])*omega__n^2*C2*(1/2))/omega__n

If I use 

evalc(Im(D1C1))

then the exp changes to sin or cos forms. How can I prevent it?

Regards,

Bahar
