I have a function that my professor wants me to type into matlab and find where it converges to zero. I am having problems with the function itself where the professor got an "error" value of 94.6008 when f = 0.0001. However, I get an error value of 87.5678 when I set f = 0.0001. I must be typing in the function incorrectly, however I do not know the correct way of typing in the function.
Here is my code:
clear all; close all; clc
error = @(f) 1/sqrt(f) + 2.0*log((0.000042/3.7)+(2.51/(126400*sqrt(f))))
answer = error(0.0001)
Here is the original assignment

Peter - try using log10 instead of log. This seems to give the desired result.
