PolarPloting by useing Mathematica

[Psi-String]

If I want to polarplot a function, say, r=cos(t) , what instructions should I type?

I tried this before:

PolarPlot [ Cos[t] , {t, 0, 2 Pi} ]

but it just brought out the same thing!

PolarPlot [ Cos[t] , {t, 0, 2 Pi} ] ,not the graph!

Where did I went wrong??

Don't put a space after PolarPlot (or anywhere else).

Your command line should read: PolarPlot[Cos[t],{t, 0, 2 Pi}]

It looks like you have the correct syntax for polarplotting in Mathematica. However, it is possible that you have not loaded the necessary packages or have not defined the function properly. Here are some steps you can follow to successfully polarplot a function:

1. Make sure you have loaded the "Graphics" and "PolarPlot" packages. You can do this by typing "Needs["Graphics`PolarPlot`"]" in your notebook or by going to the "Packages" menu and selecting "Load Package" and then choosing "Graphics`PolarPlot`".

2. Define your function using the "Set" function. For example, you can type "r = Cos[t]" to define the function r as Cos[t].

3. Use the "PolarPlot" function to plot your function. Make sure to specify the range of values for t. For example, you can type "PolarPlot[r, {t, 0, 2 Pi}]" to plot the function r from 0 to 2 Pi.

If you continue to have trouble, you can try consulting the Mathematica documentation or seeking help from online forums or tutorials. Good luck!
