i have a problem that said using computer program. to plot complex number
w(z)=z-2
- plot function as real and imaginary parts, ie... plot real part of w as a function of z = x+iy on [x,y] plane and plot the imaginary part in the same way.
-plot the magnitude and phase of w(z) as a function of z=x+iy on the [x,y] plane.
thanks for your help.
as you said,
which is the magnitude of |w(z)|=sqrt(x^2 + y^2) - 2 and the phase = tan-1(Im/Re)
as i use mathcad and set it up like below,
give x = -5,-4.9..5
y = -5,-4.9..5
z:= x+iy
w(z):=z-2
and I couln't get plot for the imaginary part, the phase and the magnitude
because of undefined variable i.
if you have any recommendation of other software, thanks a lot
