I want to solve three equations with three unknowns and display the solution on a 3D graph with two points - the roots of the equation. Help please!

Findroot() or roots() could solve three unknown systems. About plotting, I simply wrote equations according to solving of z. Regards 3Dplot_OchkovVF.sm (5kb) downloaded 7 time(s).

Is there a way to use CreateMesh() for single line xyz equations? x^2+y^2+z^2-2^2 creates a sphere in 3dplot, a finer mesh can look better. But I don't know how to convert an equation to CreateMesh(). I am asking if it is doable of course, if they are two different thing it is ok. A simple, short but inclusive tutorial would be beneficial.

Hi Overlord. If you can isolate some of the x, y or z variables, you can use this. If not, Viacheslav develops a 3D implicit plot codes for mathcad, you can see that somewhere in the mathcad forum. create_mesh_xy.sm (9kb) downloaded 5 time(s).Best regards. Alvaro.

The dots on the graphs above are a sign of my code being used. Originally Posted by: overlord I ask for a method converting a xyz function to CreateMesh() matrix. This is only possible for simple cases if the function is easily parameterizable. Edited by user 29 February 2024 22:52:29(UTC)
