How to get the Real and Imaginary part of an expression
Posted:

Hello
I need to extract the real and imaginary part of the following expression
(w=882)/(s^2+2*z*w*s+w^2)
where w and z are positive constants. s is a complex variable.
Applying Re and Im to the expression does not do much. By hand, one can easily find them.
What am I missing?
many thanks
Ed
