does ne 1 know a site that can help me with graphing in the xyz plane, not a 3d graphing site(as the one which do it for u)...i need one that will help me do it on paper. Or can some one give me a technique they use

ok thanks, but what i really want to know is a way of doin it, like if you had z = ln(3-x^2-y^2). how would you know what it looks like...i can do it but it takes ages....

The site below will explain how to draw your x,y and z axes step by step, and even tells you how to graph a 3-dimensional function. HTH

The most often used system for graphing "in 3 dimensions" is isometric projection using 30° angles to the horizontal for x- and y- axes (+30° for y and -30° for x), and the vertical for the z axis. Equal lengths in each of these directions will yield a fair representation of a perspective view.
If you use graph paper or a program like "Paint", you can approximate the angles using a rise of 4 and a run of 7 for y and a rise of -4 and a run of 7 for x. Use 8 squares for one unit vertically and √(4^2 + 7^2) ≈ 8.06 for one unit on your horizontal axes.

"The x and z axes are drawn as nonetheless the plane of the paper were xz plane. The y axis is drawn in the plane of the paper at an perspective of one hundred thirty 5° with the x axis, so as that this perspective of one hundred thirty 5° represents an perspective of ninety° in area." One unit on the y axis is 0.7 of one million unit on the others.
