Differential Calculus: Construction of the Tangent to a Parabola: 2.1: An applet illustrating how the tangent to a parabola is obtained through successive secant lines. Functions with Corners: 2.1: ...

2.1: Some examples of graphs with corners which I talked about in lecture. The tangent line to a graph does not exist at a corner. Algebraic Simplification: 2.3: When computing the limit of a function ...

When I took calculus at night school with three nerdy high school friends, graphing calculators did not exist. Johns Hopkins University mathematics professor Stephen Wilson is happy for me. He ...

For example, by using the graphing and zoom features of the graphing calculator, students could compare and contrast the local and global behavior of functions such as y = x² and y = x² + 2.
