Hello,
i'm having some trouble identifying the correct method to approach a problem. I don't have any working to show, so i'll explain why I think the methods I've considered are not correct.
Integrate with respect to [itex]x[/itex] the following functions.
[itex]\int \frac{x}{(3-x)^{7}} dx[/itex]
I think the method of changing the variable is not suitable here because I can't see a link between the derivative of the denominator and the numerator.
Similarly I don't think it is possible to use the method that identifies the numerator as the derivative of the denominator allowing you to say the integral is equal to ln|f(x)| + c
I'd really appreciate a nudge in the right direction!
Thank you,
BOAS
