Hi Carl,

Thanks for your prompt response.

I am not able to understand the sentence "For example, you can set it to 0 and solve it, getting three simple solutions with no RootOfs."

How to achieve this.  I have use eval(%, _Z =0).  The output of this command is still having the RootOf.

Could you please enlighten me.

Thanks.

Hi Carl,

thanks for your reply. I realized that the title might be miseading. Sorry. Please let me re-define the problem.

My function has 3 variables (a,b and c) and some constants.

After some re arranging, , the equation takes the form  a = f(b,c).

My goal is to find da/db =0 and solve for b ( which is nothing but finding the extremum) and substituting value of b in f(a,b) to get the function f to be a sole function of  variable c. This is to get the relation between  variables a and c.

However, while solving for variable b, i am encountering the RootOf( _Z,.....).

From my reading  RootOf means the equation might br tranwcandel equation.

Hence i presume only a numerical solution exists. Please correct me if i am wrong.

Thanks for taking time in responding.
