Calculus connects: teaching IBDP aligned Calculus with Wolfram Demonstration​

​International School, Tanzania
The International Baccalaureate Diploma Programme (IBDP) is a two-year educational programme primarily aimed at 16-to-19-year-olds in 144 countries around the globe. Calculus is one of the major topic in mathematics which is a compulsory subject for graduating students. This document provides an extensive list of highly interactive and revealing Wolfram demonstrations that can readily be utilized in teaching Calculus in the class .

Introduction

High school math teachers are consistently put to the test when it comes to teaching Calculus. Traditional techniques and tools make it exceedingly difficult to instruct a clear picture of the various concepts in Calculus.The subject, however, can be made significantly more approachable, relevant and meaningful using Wolfram Demonstrations. The Wolfram Demonstrations Project is an open-source project that use dynamic computation to explain calculus principles. The purpose of this notebook is to list and provide a collection of the demonstrations that may be beneficial in International Baccalaureate Diploma Program (IBDP) Calculus course. The freely available CDF player can also be used to explore currently available demonstrations.
​
The notebook is divided into 5 sections. It begins with some resources that may be explored prior to beginning Calculus teaching, and it includes the idea of Tangent line from an algebraic standpoint, as well as Zeno’s paradox to motivate and encourage learners to reflect about the concepts of infinite and limitations. It also encompasses the investigation on exponential and rational functions. The second section addresses the concepts of limits and continuity. The concept of derivatives and their applications is thoroughly discussed in the third and fourth sections, while the fifth and sixth sections cover integration and its applications.

Getting Started

Find the tangent line to a parabola without using Calculus

To begin, it is a good idea to apply pre-existing Algebra ideas to evaluate the equation of tangent on the parabola at a certain point. It is found by solving simultaneous linear and quadratic equations and setting the Discriminant to zero. This presentation gives the learner a thorough knowledge of how tangent lines behave.

There is a neat method for finding tangent lines to a parabola that does not involve calculus. In this problem, for example, to find the line tangent to
y=

at (1, -2) we can simultaneously solve
y=

and
y+2=m(x-1)
and set the discriminant equal to zero, which means that we want only one solution to the system (i.e., we want only one point of intersection).

​
Zeno of Elea (circa 450 BC) is credited with creating several famous paradoxes, but by far the best known is the paradox of the tortoise and Achilles. A fleet-of-foot Achilles is unable to catch a plodding tortoise which has been given a head start, since during the time it takes Achilles to catch up to a given position, the tortoise has moved forward some distance. But this is obviously fallacious since Achilles will clearly pass the tortoise!

The Concepts of Limits

​
A semicircle of radius 1 and its diameter are approximated by two families of curves, which converge to the arc and the diameter in the limit. The areas between the jagged lines and the limits tend to 0 as grows. The sum of the lengths of the jagged lines of the first family tends to the length of the arc of the circle. But the sum of the lengths of the broken lines of the second family does not tend to the length of the diameter.

The Concepts of Derivative

Secant and Tangent Lines

To understand the idea of slope of the tangent line, it’s vital to understand the concepts of secant and tangent lines: this demonstration illustrates the connection between the secant line and the tangent line at a point on the curve

Derivative as a function

Graphing the Derivative

After understanding the idea of secant and line ad tangent line, the student are tasked to find the derivative graphically:

This Demonstration illustrates the connection between a function and its derivative on two separate graphs. The green vertical bars indicate the value of the rate of change at the point of tangency.

A dog fetches a ball thrown into a lake. Because the dog swims more slowly than it runs on sand, the shortest time path is not a straight line. You can drag the image of the dog to vary the path.
