Integrating xy

  1. Nov 6, 2008 #1
    1. The problem statement, all variables and given/known data
    It is simple: find the antiderivative of 2xy.

    2. Relevant equations

    3. The attempt at a solution
    I am inclined to say that it equals (xy)^2 +c, but can't help but feel i have left out something.

    What are you integrating with respect to? Are both x and y variables?

    Yes, they are both variables.

    Then answer the question! You want to find the anti-derivative with respect to which variable?

    [tex]\int 2xy dx= x^2y+ C[/tex]

    [tex]\int 2xy dy= xy^2+ C[/tex]
