What conditions are necessary to apply Fubini's theorem?

• The function to be integrated must be derivative with respect to each of the variables

• 
  The integrable function must be integrable with respect to each of the variables separately.

• 
  The function being integrated must be unlimited

• The function being integrated must be linear

What are the limits of integration?

• 
  Difference of function values

• Sum of all function values

• The interval over which the function is integrated

• Derivative of a function

Answer explanation

The limits of integration refer to the interval over which the function is integrated. It determines the range of values for which the function is evaluated.
