Need some help with some mathsy stuff...
OK I need some help re-arranging a formula.

This is it:

[Image: 4hrwv9.gif]

It basically calculates the resonant frequency of an incuctor-capacitor network in a filter. i.e. a radio reciever.

I need to work out C. I can re arrange basic equations but this is way above me. You all seem reasonably intelligebt. Anyone here able to work it out?

By the way: I used THIS for rendering the equation into an image. Takes a bit of getting used to but it's pretty useful one you learn how to use it.

Your spoon is complex.

(f0 squared) divided by (L times 2 times pi) = 1 over C

Does this help? I'm assuming you know what L and f0 are.

Is that it?

Physics and Geometry are my best subjects.
