Plotting Phasor representations of functions

Click For Summary
SUMMARY

The discussion focuses on plotting phasor representations of the function y(x, t) = 2cos(π/6 t - π/4 x) for x ranging from 0 to 8. The phasor representation is given as ŷ(x) = 2e^(j(-π/4 x)), which indicates that the plot will depict a circle in the complex plane with a radius of 2. The angles of the phasors are determined by -π/4 x, illustrating the relationship between the spatial variable x and the phasor's position on the circle.

PREREQUISITES
  • Understanding of complex numbers and their representation in the complex plane
  • Familiarity with trigonometric functions and their phasor equivalents
  • Knowledge of plotting functions using software tools like MATLAB or Python
  • Basic principles of wave mechanics and oscillatory motion
NEXT STEPS
  • Learn how to use MATLAB for plotting complex functions
  • Explore Python libraries such as Matplotlib for visualizing phasors
  • Study the relationship between time-domain functions and their phasor representations
  • Investigate the implications of phase shifts in waveforms and their graphical representations
USEFUL FOR

Engineering students, electrical engineers, and anyone interested in understanding and visualizing phasor representations in wave mechanics.

Homework Statement



Plot the following for x = 0 to 8:

This is part of a larger engineering problem, but I am stuck here, I have no idea how to plot a phasor.

The original function is:

[tex]y(x,\,t)\,=\,2\,cos\left(\frac{\pi}{6}\,t\,-\,\frac{\pi}{4}\,x\right)[/tex]



Homework Equations





The Attempt at a Solution



And the phasor representation...

[tex]\tilde{Y}(x)\,=\,2\,e^{j\left(-\frac{\pi}{4}\,x\right)}[/tex]

How do I plot that?!?

The plot will be a circle in the complex plane of radius 2. The phasors will be points on the circle with angle given by [itex]- \frac{\pi}{4} x[/itex].
