Mathematica Plotting Functions in Mathematica: A Simple Guide

[clanijos]

Could someone tell me how I would go about plotting a function in Mathematica over say, x^2? or sqrt(x)?

Thanks!

Perhaps more appropriate posted here:

To do this use

Plot[x^2,{x,-3,3}]

which is documented here

http://reference.wolfram.com/mathematica/ref/Plot.html

or when you are running the software hit <f1> and when the help browser pops up type in Plot or any other likely keyword you want documentation on.

Mathematica is fanatic about exact use of {} versus [] versus (), := versus = versus == versus even === and correct capitalization. Make an error in anyone of those and you will get possibly incomprehensible error messages.

Thanks!

Edit: Gah, replied before I really looked over what you said! Yeah, I know how I should go about plotting a function like that. What I am looking for is something similar to LogPlot, but where the scale of the x-axis can be changed to another function.

You want to compress the scale on the x-axis, but not logarithmically? It's difficult to see why you might want to do that. I think you would have to do the compression yourself and then re-label the axis after the computer has done the plotting.

Exactly what are you wanting to plot?
