    Post 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:

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


    <br />
G = \frac{2L}{\pi r^4}C

    and rearrange them to get C

    thanks

    [QUOTE=dadon;34420]Hey guys!

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

    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...
