Homework Help: Simple integration

  1. Jan 12, 2008 #1
    1. The problem statement, all variables and given/known data
    I know the integral of 6/(x^2) is 6/x but what are the steps to achieve this...

    2. Relevant equations

    3. The attempt at a solution

    Does it involve the substitution u=(x^2) then what is the next step......

    What is the derivative of your substitution? Does it appear in your original Integral?

    Try re-writing your Integral as [tex]\int6x^{-2}dx[/tex] do you see what to do next?

    Oh ofcourse - you would then say add one to the power and divide by the new power which becomes -6/x

    thanks - (i must have had a mental block :) )
