Hello everyone!
I started using Mathematica today (have only a little bit OF Matlab experience).
I got the following code:
r[x_]= 2x / (x^2+1)^2;
s[x_] = (x^2 (-1+x^2))/(1+x^2)^2;
ParametricPlot[{r[x],-s[x]}, {x,0,10}, PlotStyle -> {Blue},
AxesLabel->{Style[r,Large],Style[s,Large]},LabelStyle->Directive[Bold]]
My task seems to be quite easy, but I fail: I want to get this plot, but only with positive s-axis - no negative s-values needed.
Can anybody help me, please?
Thank you so much!
