3 Variables Cubic Polynomial

HELLO,

Please help me to construct a cubic polynomial with 3 variables.

I am trying to make a cubic polynomial from the function Zf with 3 variables, namely Rho, Alpha andX0

I have attached the worksheet (MathCad 14), so, any help would be greatly appreciated.

Thank you,

Why have you created a second thread?

Is this not the same problem as the first?

Hello Mike,

This is the same problem. I had problem creating 3D graph. This is now solved.

I need to write the actual cubic polynomial using the function Zf. No one answered me before, that's why there is another thread.

I need help on this.

Thank you so much

Just because someone hasn't replied doesn't mean you won't get a solution.

I have saved your Mathcad worksheet down to M11 format for a wider audience.
