This lecture the topic is Integration. First we will explore the concept of integration by looking at the Prêt-a-loger example: turning an existing house into a sustainable one. You will learn the definition of integration by Riemann sums. Then we will discuss the fundamental theorem of calculus to define the relation between integral and derivative. We will review the primitive functions of x^n, e^x, sine and cosine. You will apply the rules of calculation.

We finish this lecture with a university preview on integration of functions with more than one variable.
