    Logarithmic Trendline Equation

    I have a logarithmic trendline with the equation Y = 533371Ln(x) - 3E+06
    associated with a line series. I want to create another series using this
    equation (substituting 1, 2, 3, etc. for x) but don't know what "3E+06"
    means, or how to set the equation up as a formula. Can someone explain the
    equation and show me how to set up my formula series?

    Thanks,
    Phil

    Re: Logarithmic Trendline Equation

    This is so-called scientific notation; 3E+06 would be written by hand as 3 x
    10 (power of 6). Of course this is 3,000,000 or 3 million

    In A1:A10 enter 1,2,3...10
    In B1 enter =533371*Ln(A1)-3E+06
    Copy B1 down to B10
