Mathematica help

  1. Oct 14, 2008 #1
    I'm trying to plot this
    f (x, y) = ln(x^2 + y^2 )

    any one got a idea how to?

    Plot3D[f, {x, xmin, xmax}, {y, ymin, ymax}]
    make a three-dimensional plot of f as a function of the
    variables x and y

    More accurately,

    Plot3D[Log[x^2 + y^2], {x, xmin, xmax}, {y, ymin, ymax}]

    or

    f[x_,y_]=Log[x^2 + y^2]
    Plot3D[f[x,y], {x, xmin, xmax}, {y, ymin, ymax}]

    i want to make this symmetric in both x and y with 2 graph by using the cartesian coordinate system with the plot3D command and secondly using the cyclindrical coordinate system using the parametricplot3d command. been a long time since i've used mathematica but i don't think your codes does the above right?
