Graphing in 3d

  1. Oct 10, 2012 #1
    I am really struggling graphing in 3d. here are main problem.

    I graph out using trace curve, for z=k, x=k, and y=k, each one of them, and I was unable to put them together and generate a 3d picture.

    For instance, z=xe^(-y). This function is a very weird sheet with two sides tilt in opposite direction.

    I just want to seek some suggestions from you guys as to how to graph out this function by hands, or by calculator. What other techniques could I use? How could I improve on my graphing.

    Thank you
