Question

Find the indefinite integral.
6x^5/(x^6+4x)^2

There is an integral sign in front of the equation i just could not add it

Answer 1

[S] works for an integral sign

Answer 2

if we substitute u = x^6 +4x; du = 6x^5 + 4 dx

Answer 3

it is actually 6x^5 +4 / (x^6+4x)^2

Answer 4

well thats helpful ;)

Answer 5

then we end up with a substitution that is:

[S] 1/(u^2) du

[S] u^(-2) du which is doable right?

Answer 6

do you see hoe that happens?

Answer 7

rite. okay so then u would get -1/x^6+4x

Answer 8

plus the constant

Answer 9

yes :)

Answer 10
