Plotting complex equations on the Argand plane with Wolfram Alpha

Click For Summary
SUMMARY

This discussion focuses on plotting complex equations on the Argand plane using Wolfram Alpha. Users have found that directly inputting complex equations, such as $|z-1|+|z+1|=5$, does not yield the desired graphical output. Instead, converting the complex modulus into a real plot format, such as $\sqrt{(x-1)^2 + y^2} + \sqrt{(x+1)^2 +y^2} = 5$, is recommended for effective visualization. Additionally, the challenge of plotting higher-order complex equations like $$(z-1)^{25}=2\omega^2(z+1)^{25}$$ is raised, indicating a need for further exploration of input methods.

PREREQUISITES
  • Understanding of complex numbers and the Argand plane
  • Familiarity with Wolfram Alpha's input syntax
  • Knowledge of converting complex equations to real-number formats

I am wondering how one would go about drawing graphs in Argand plane using Wolfram Alpha. For instance, I want to plot an ellipse $|z-1|+|z+1|=5$ using W|A, what should be the input? Simply entering $|z-1|+|z+1|=5$ doesn't give what I want.

Thanks!

Wolfram|Alpha doesn't seem to do well with complex plots.

What I would do is take the square root of the modulus and turn it into a "real" plot, like so:

$\sqrt{(x-1)^2 + y^2} + \sqrt{(x+1)^2 +y^2} = 5$

Yes, I know I can enter that but that was just an example I stated in my post. How would I go about plotting

$$(z-1)^{25}=2\omega^2(z+1)^{25}$$

:confused:
