Meaning of the word integral

  1. Mar 27, 2012 #1
    I've seen the word used in a context that is not related to calculus, but I never understood what it meant. What does it mean if an equation has an integral solution?

    Here is a context:If X^2 +Y^2 = 2aXY has a positive integral solution, find the value of a. What does it mean to have an integral solution?

    It means that the solution is an integer.

    It means that all the variables involved have their roots in form of integers.

    As stated above, I believe that the solution is an interger (i.e. you won't have decimal or fractions as an answer).

    That's integer, but you are otherwise correct.
