Finding the DerivativeDate: 07/27/99 at 12:11:11 From: Kayla McLean Subject: Finding the Derivative y = A*(1-e(-cN))* (1-e(-cM)) Can you help me take the derivative of this function with respect to N? When I did the problem, I left out the A because it is a constant. I ended up with something like this: dy/dN = (1 - e(-cN))* (1/e(cM)) + (1 - e(-cM))*(1/e(cN)) Date: 07/27/99 at 13:30:17 From: Doctor Rob Subject: Re: Finding the Derivative Don't leave out the A, but carry it along as factor. Remember d(c*u)/dx = c*du/dx, if c is a constant. Also, (1 - e^(-cM)) is a constant too, since it does not depend on N. Now try again. - Doctor Rob, The Math Forum http://mathforum.org/dr.math/ |
