    Maybe a simple question. Hope someone can help.

    Hi all,

    Can someone help me here?

    I forget the name of what I am doing. For a start someone might revive my memory. I need to find the value of a variable by honing in on it. Bounching closer to it with each iteration.

    The attached drawing might help. I know the values of the two perimeter lengths P1 and P2. But I need to adjust the P1 circle to get to P2 by adjusting the value of a.

    At the moment I have
    a=a*(1+(P1-P2)/P1)
    but its not getting me there fast enough.

    Any suggestions?
