Limit of Functions,In Chapter III we dealt with limits of real sequences. These are real-valued functions whose domains are essentially ℤ. or ℤ.. In this chapter we treat limits of real-valued functions of a real variable whose domains are not necessarily confined to ℤ. or ℤ.. Of special interest are functions whose domains are intervals.

Derivatives,Limits often arise from considering the derivative of a function at a point.

The Riemann Integral II,We now consider the legitimacy of passing to the limit under the integral sign. If the sequence 〈.〉 of .-integrable functions converges to a limit . on an interval [., .] does it necessarily follow that
