I want to scale the x-axis in the plot by a factor of $\frac{\sqrt{3}}{2}$, When I change the variable in the command:
Plot[f,{Sqrt[3]r/2,0,20}]
I am getting an error as "tag Times in $\frac{\sqrt{3}r}{2}$ is protected"
How to remove this problem?
ParametricPlot[{Sqrt[3]r/2,f[r]},{r,0,20}]
$\endgroup$
