system of equations

Hello,

 

I would like to solve a system of equations, but I receive the error "The symbolic result is too large to display". I need the symbolic result, because I would like to calculate the parameters of the electric circuit for which I wrote this system of equations. I'd appreciate it if you could help me with this issue.

 

I have attached the relevant file.

 

Thank you.

Marius

As your sheet is too complex for me to edit and show what I mean, here is a simple worksheet with some thoughts and explanations.

Hi Valery,

 

I tried to do attribution, but it didn't work.

You can turn the result into a function of the unknowns.

 

Use "result(xIcb0, xbeta,xR1043,.....) := [  ] solve... "

You will still get the message about the expression being too large, but you can use that function an can evaluate it numerically for any value of the unknown variables.
