=== Objectives ===
To enable students to,
# understand the process of anti-differentiation.;
# recognize the problem of calculating areas bounded by non-linear function;
# understand how the limit of the sum of rectangles may be used to calculate the area bounded by a function;
# understand the meaning of <math>\textstyle \int\limits_{a}^{b} \displaystyle f(x)dx</math>;
# calculate the area under a function between two extremes;
# apply knowledge and skills relating to anti-differentiation to solve problems;
# verify that the area bounded by the curve y=f(x), x=a, x=b and x-axis =<math>\textstyle \int\limits_{a}^{b} \displaystyle f(x)dx</math>
