New Solve for x

[RDokken]

I have a 4th degree equation which I have solved for and obtained x.

Using the solve function along with "assume", I filtered out only the positive answer to the equation.

Mathcad displays my answer, but how do I get it to allow me to actually assign that answer to my variable "x" for use in further calculations?

Thanks for your help!

You need an additoinal numeric assignment. See the attached worksheet.

Helpful, but not quite what I was asking.

I should have attached my worksheet.

I have now attached it. What I need to do is take the solution for the equation (the 13.8552...), assign it to a variable, and continue on, using that solution in further calculations.

Actually I think I stumbled on the answer, based somewhat on the info you provided. It is attached.

Thanks!

Yes, That is correct. The example I gave was for a function assignment but it works the same way for a variable assignment.

Your problem is that deg is a unit, further symbolics don't know its value. Define it before assignations (as deg:=0.017453292519943, and the symbolic assignation for X works fine.
