This interactive demo illustrates complex sinusoids e^jwt=cos(wt)+jsin(wt), in 3D animation plot showing the relationship between complex plane, real axis and imaginary axis.
The reset button replay the animation
The popup menu allows the user to switch the view between 3D view, Real axis, Imaginary axis and Complex plane
I would like to acknowledge James McNames for inspire me to write this script based on his lecture slide.
