M Morts Member Oct 6, 2005 #1 How do I take the derivative of a function with an absolute value in it? For example, I'm dealing with f(x) = (1/(1 + |x|)) + (1/(1 + |x - 2|))

S Shompola Banned Oct 7, 2005 #5 |x| = x * ((sign of x) 1) |x-2| = (x-2) * (sign of (x-2) 1) this is atleast the definition of absolute value for real numbers. Take this in account when derivating.
