Need help with maple programming

  1. Nov 20, 2015 #1
    I can't input this formula,

    z=(1+x^2)/(1+y^2)

    This is suppose to represent a function of surface of area with double integrals. I'm struggling inputting the codes in to evaluate the equation.
    It would be convenient if help was given

    Thank you for trying to help but that won't help too much

    It is unclear to me what you are trying to do mathematically, i.e. even without thinking yet about how to input it in Maple. Could you explain more?

    The area of the surface with equation z

    Don't you have any boundaries given for the surface? If not, the area is infinite and it is pointless to calculate it with Maple. If your task is written somewhere, please let ut know the exact wording.

    Your suppose to find the area of the part of the surface that lies above square lxl +lyl < 1
    and draw a graph

    It didn't help, this is the type of cal 3 problem that im referring to http://tutorial.math.lamar.edu/Classes/CalcIII/SurfaceArea.aspx.

    z=(1+x^2)/(1+y^2)

    I'm suppose to find the area of the part of the surface that lies above square lxl +lyl < 1
    and draw a graph

    and I can't seem to find the right code to put in to solve equation

    First, differentiate z w.r,t x and y, with Maple. Plug these partial derivatives into your formula for (the element of) surface area. Then evaluate with Maple the double integral of this over the region I suggested and multiply by 4.

    I'm a bit late to this discussion, but are you just having syntax problems? For example the assignment statement should be z:=(1+x^2)/(1+y^2); Note the colon and the ending semicolon. Then the partial with respect to x would be something like zsubx := diff(z,x);
