Question

find the derivtive xe^2x + 3.

Answer 1

well 3 is a constant so it's automatically zero...just use product rule + chain rule on xe^2x

Answer 2

what is the derivative of e^2x?

Answer 3

e^2x

Answer 4

the chain rule part would be 2

Answer 5

Almost. Chain rule says that you have to multoply by the derivative of 2x.

Answer 6

Yuss.

Answer 7

good so it's 2e^2x

and the derivative of x?

Answer 8

1

Answer 9

good product rule states that it would be

x(derivative of e^2x) + e^2x (derivative of x)

derivative of e^2x is 2e^2x and derivative of x is 1 so

x(2e^2x) + e^2x (1)

2xe^2x + e^2x

you're following right?
