Question

dv= 8x^2dx, what is v=dx? Please help

Answer 1

Don't really understand this, let's integrate so

v = 8x^3/3 + C

Does that help?

Answer 2

if i may ask how would you know..i dont know how i would get 8x^2dx

Answer 3

"i dont know how i would get 8x^2dx" ????

You gave this in the question.....

Answer 4

yes but im asking how would you derivrate 8/3 x^3 to 8x^2?

Answer 5

Ah, OK.....

v = 8x^3/3 + C so

dv/dx = 3* 8x^(3-1) / 3

Answer 6

In general, ax^n

dx = n*a * x^(n-1)

Answer 7

oh ok i see thanks so much!!

Answer 8

ur welcome
