Question

y= x sqrt(2x+1) Product rule?

Answer 1

youre going to have to be more "descriptive"

Answer 2

I need to find the dy/dx. I was told I just need to set up up the problem using one of the rules (chain rule, quotient rule, etc)

Answer 3

Presumably you want to differentiate it by the product rule?

Answer 4

He's trying to take the derivative

Answer 5

You will need the product and the chain rules.

Answer 6

First you will use the product rule because it's a product. Then when you are looking for the derivative of the square root factor you will need to use the chain rule.

Answer 7

Can you show me how? Sqrt's confuse the heck out of me. :(

Answer 8

Well first use the product rule. What will you have?

Answer 9

Don't evaluate the derivative of the square root yet if it scares ya ;)

Answer 10

I would probably change that square root to an exponential fraction first

Answer 11

Sure. Comes out the same way though.
