equation problem

[wanglm]

In the equation: , Q is known, how to get the f value in LabVIEW? Thanks a lot~

Hi wanglm,

  Probably i am just guessing for this problem.If Q=1,then f should be =1...

If you know how to transform your equation to f = ..... then you can calculate f by using the formula node structure. Check out the detailed help from this structure or even an example VI if you are not familiar with it.

Or is the converting of your equation the problem?

This is an algebra issue, not a programming issue.  Solve for f.  You can then easily make your program by following that equation.

At first glance it is not clear whether your equation has an analytic solution. You may need to consider an iterative numerical solution technique.

Oh, you are right, I just don‘t know how to convert the eqution to f=…, and wondering whether LabVIEW can do it.

Or maybe I shoud learn some math thanks~

There are plenty of people who can convert this for you, but if you use formulas like these on daily basis you should learn some math indeed ;). I'd suggest to rather consult a mathematics forum instead of the NI forum for the conversion although I'm sure there are people on this forum who can convert this one.

I'm also working on a project where I use math which oversteps my knowledge, but with some research I did learn a lot and there are always guys who will help you if you're stuck.

Kind regards
