Solving a function with indices
Solving a function with indices
(OP)
I'm having trouble getting an iterative equation to solve. I can do it manually, so there is an answer, but for some reason MathCAD won't solve
1.552 = (V1 + 10)^1.4 / V1^1.4
It also works fine if I remove the indices
1.552 = (V1 + 10)^1.4 / V1^1.4
It also works fine if I remove the indices

RE: Solving a function with indices
The first question is why you're using the symbolic solve, given that you obviously need a numerical answer, and the algebraic solution of your question is relatively trivial.
You ought to be using either Given-Find or Given-Minerr, as shown in the attached sheet. Minerr generally will be more tolerant of ill-formed equations, while Find requires the solution to be within the default tolerances set within Mathcad. Minerr will usually find a solution that only minimizes the error.
