Find the derivative for these:= 6

yxe^{−kx So for this I'm getting 6-ke^x }

y= (square root the whole equation)

This one I'm not entirely sure how to do, maybe (a-b)^2?

Your question's pretty unclear, but I'm assuming you want to find dy/dx?

For the first one, you have to use the product rule:

, then simplify.

The second one's just a chain rule problem. I don't know what you're referring to when you say ... - Oct 23rd 2012, 06:38 PMOldspice1212Re: Derivative
Sorry about that, it's fixed, yes it was to find the derivative for these questions :P

So is the first one e^-kx(6-6kx)?
