Imagpart

Function: imagpart (<expr>) Returns the imaginary part of the expression <expr>.

V(t):=100000/(1+%i*t/(2*%pi*10));
plot2d(20*log(sqrt(realpart(V(t))^2+imagpart(V(t))^2)), [t,0,100000], [gnuplot_preamble, "set log y"]);

imagpart is a computational function, not a simplifying function.

See also abs, carg, polarform, rectform, and realpart.
