Seems simple to me. Check out what the terms in the mathematical expression above really mean (variable definitions, in which respect the expression is being solved, and limits...), and you will see that your question is readily answered.

Still in doubt? Replace f(t) by a simple function and calculate the expression. Piece of cake.

Sorry, but we do not solve homework questions. You already had a tip and I've spoken too much.
