Question

what is the integral of vdv

Answer 1

power rule ?

Answer 2

\(\int v dv\)?

Answer 3

yes

Answer 4

what do you need to differentiate to get v?

Answer 5

ye

Answer 6

that was a question:)

Answer 7

\[\Large \color{blue}{\int\limits_{ }^{ }\rm v~dv}=\Large \color{blue}{\int\limits_{ }^{ }\rm 1v~dv}= \frac{v^{1+1}}{1+1}=?\]

Answer 8

\[v ^{2} ?\]

Answer 9

close, try again

Answer 10

if you differentiate v^2 you get 2v

Answer 11

but in general look at what @SolomonZelman, I was just trying to show you the connection to something you already know how to do

Answer 12

yes, and your answer will be ?

Answer 13

v2/2 + c?

Answer 14

correct

Answer 15

yes

Answer 16

good that you didn't leave out +C

Answer 17

ok thnks im just refreshng ty

Answer 18

Anytime, I am also a trig student. I've solved some harder integrals but I don't think I got a grip on them so much :)

Answer 19

and remember the power rule does not work for x^{-1}, just remember it lnx
