Question

Check my few Calculus questions?

Answer 1

Answer 2

Might get faster results if you were to post only one problem at a time.

What have you considered doing in the first case?

Answer 3

Using chain rule I got −x^2−11/x^3+11x but that isn't a choice...

Answer 4

You have the second question right

Answer 5

Need to use rules of logs to simplify this work. You are given the ln of a fraction.

Which rule would you use to break this up into 2 parts?

Answer 6

Not wanting you to hate calculus any more than you already do, of course, but please label your results. Was your result the simplification of the given function or was it supposed to be the derivative?

Answer 7

The derivative.

Answer 8

Need to see how you obtained that.

As i said before, ln (a/b) can be broken into two parts. What are they?
Use the same rule of logs to break up the given function into 2 parts.

Answer 9

not sure about the log part but i used chain rule ddx[f(g(x))]=f'(g(x))g'(x). to get the other answer i showed.

Answer 10

You might be shocked at how much easier it would be to apply rules of logs instead of the chain rule here.

Please break ln (a/b) into two parts, using the rule of logs applying to division.

Answer 11

you really need to break the log part up first

Answer 12

I see thesecond one is right the first one should be C/

Answer 13

not sure how to break it into two can you explain/show me how to?

Answer 14

I'm sorry , Calc, but you'll have to show your work if you want my feedback. i just don't do "C" ...

Answer 15

Have your calculus or algebra book handy? If so, look up "rules of logs" and find the rule applying to (a/b).

Answer 16

Note that welshfella is pushing the same approach: apply the appropriate rule of logs.

Answer 17

looking at my book now i send u a amssg

Answer 18

as before: Please look up "rules of logs" in your textbook. Then look for the rule that applies to the log of a quotient. ln (a/b) = ln ????

Answer 19

I redid it with welsh and got D for the answer using chain rule... I was just not putting the fractions in right .

Answer 20

Fine. Glad you got the answer you wanted. Still, I think you should make a point of learning those rules of logs and how they apply to simplify differentiation of functions involving ln.
