1. The problem statement, all variables and given/known data -∞ ∫f(t)dt a b ∫f(t)dt -∞ b ∫f(t)dt a Now add the first two integrals, do we get the third integral? 2. Relevant equations N/A 3. The attempt at a solution Suppose we have c ∫f(t)dt a b ∫f(t)dt c b ∫f(t)dt a Then adding the first two integrals will give the third integral, but what happens in the case of improper integrals?
