I have to make a program which can identify the expression for example
V1=V2+P1, V1>i1(P1) or V1=(P1+P2)/V2
where V1,V2, P1 and P2 are variables. user will enter values of these variables first and then he will make an expression. My program will have to solve that expression.
in other way it is totally up to the user what expression he wants. I will really appreciate if somebody will help me.
