    Rearrange Formula

    Hi, this is probably dead easy for most of you but can you help me re-arrange this formula so that CC are the subject.

    The formula is:
    F= 1/(2π√(R R C C))
    F equals the inverse of two pi times the square root of R x R x C x C
    Thanks

    Square it, multiply by C_0 C_1 and then divide by F^2.

    Thanks but my maths sucks.
    So if someone could just tell me what equals, that'd be great.
    This is for an extensive project building a graphic equalizer and I'd really not waste time stuck on something like this

    Hi J4553

    I think it's better if you try it by yourself. Matt Westwood's advice is excellent !

    F=\frac{1}{2\pi\sqrt{R_0 R_1 C_0 C_1}}

    Steps (as suggested by Matt Westwood) :
    1. Square both sides

    2. Multiply both sides by C_0 C_1

    3. Divide both sides by F^2

    Ok I got =/(2 π x R x R)

    Yes / No / Way Off?

    Hi J4553

    Your answer is wrong ^^

    F=\frac{1}{2\pi\sqrt{R_0 R_1 C_0 C_1}}

    If you square both sides, you'll get :

    F^2=\frac{1}{4\pi^2{R_0 R_1 C_0 C_1}}


    Then, multiply both sides by C_0 C_1 will give you :

    F^2C_0 C_1=\frac{1}{4\pi^2{R_0 R_1}}


    Finally, Divide both sides by F^2 will give you....^^

    Second attempt...

    =/(4 π x R x R)

    Hi J4553

    Still wrong ^^

    F^2C_0 C_1=\frac{1}{4\pi^2{R_0 R_1}}

    Divide both sides by F^2 will give you :

    C_0 C_1 = \frac{1}{4\pi^2{R_0 R_1}F^2}
