1. ## Rearranging Equ.

Hey guys!

Happy New Year! hows it going so far? hope its going good!!

I wanted to know how you use these 2 equations:

$\displaystyle T = 2\pi\sqrt\frac{1}{C}$

$\displaystyle G = \frac{2L}{\pi r^4}C$

and rearrange them to get C

thanks

Happy New Year! hows it going so far? hope its going good!!

I wanted to know how you use these 2 equations:
$\displaystyle T = 2\pi\sqrt\frac{1}{C}$
$\displaystyle \frac{T}{2\pi}=\sqrt{\frac{1}{C}}$
$\displaystyle \frac{T^2}{4\pi^2}=\frac{1}{C}$
$\displaystyle \frac{4\pi^2}{T^2}=C$
$\displaystyle G = \frac{2L}{\pi r^4}C$
$\displaystyle \frac{G \pi r^4}{2L}=C$

3. hey thanks for that the perfect hacker!!

sorry but in the equation when t equals it was meant to be a "I" instead of the 1.

does that change the method? if it does what do u need to do?

thanks again

Since the "1" hasn't been squared or anything bizzare it is just a placeholder in the equation. So you can get away with substituting the "I" for it.

Actually it would be a good exercise for you to redo TPH's work yourself using the I...
