You have all of the variables in hand except the one you want to calculate. It should be a simple algebra problem from there.

So would it be (f*2pi)^2 =1
.........................L ......=C

But how do i get rid of the 1 over the c?

Should i just use the reciprical of both side?

......L .....=..C
(f*2pi)^2

Right?

am about to give you the correct formula, but i guess it won't help. why dont you put reasonable values on the original formula and work your way backwards and see if you get the correct values thru your reformulation.

More like this:

$C=\frac{1}{L(2\pi f)^{2}}$

1/x=1/y

multiply both sides by x*y

x=y
