Homework Help: Can some one show me how to do dy/dx?

  1. Mar 13, 2007 #1
    What is the Integral of 1/((x+5)^2(x-1)) AND (x^3)/(x^2+1) ?

    I only need some one to show me an example!

    Show Detail and Steps Please!

    Thank to all !

    I know I need to use partial fractions but I am stuck on those two

    Do you mean integral or derivative? Your topic title says derivative, but you say integral.

    OH the Integral

    Alright, I can't do the homework for you, so you are going to have to take a leap somewhere.

    Just remember that you want to take some fraction and decompose it into two separate fractions, the reverse of simplification.

    1/((x+5)(x+5)(x+1)) and other one no idea
    This is not homework, just want to know how to do it!

    <tex> 1 \overline {(x+5)(x+5)(x+1)} <\tex>

    To do partial fractions for the second one the degree of the numerator has to be less than the degree of the denominator I believe... So divide first, then go from there.
