    Name of function

    Hi,

    I have the following function:

    e^(f1+f2r+f3r^2+f4r^3+f5r^4+f6r^5)

    I am wondering what the proper name for it is (as I am giving a presentation in a few days)...

    [is it as simple as 'a fifth order exponential'?]

    Thanks

    If I were you, I would write as $\displaystyle \exp \left( {\sum\limits_{k = 1}^6 {{f_k}{r^{6 - k}}} } \right)$

    I doubt there is any accepted name for this. But you should use the word "degree" rather than "order" for the polynomial.
