    Graduate Fourier Transform and zero wave-vector

    I am not sure if I am crazy, I am not a mathematician or physicist by training, but I recall doing some work where if I was interested in the limit of a function in "r space" as r-> Infinity I could just use the value of the function in "k-space" at 0 to get the value I was interested in. Is...

    Undergrad Solve y=1- A(1-e^(-kx)) + mx +b

    At work today one of the biologist came and asked me with help on solving a problem. I need a little hint as I still would like to solve this problem. y=1- A(1-e^(-kx)) + mx +b A, k, m and b are all constants I need to solve for x but it results in getting a -kx-ln(x) = some junk From...
