Programming a simulation on the TI-nspire calculator

This video shows the basics of writing and running a simulation in Python. It demonstrates coding using the replit.com online Python environment, although the same code could be used in other Python settings (e.g. if Python is installed on someone's computer).

Deciding which activities should be used to reduce the overall minimum completion time of a project.

Given two rules like y = x² and y = -(x 4)² 2, find the transformation that maps one to the other and then sketch the result.

Finding the shortest path in a graph/network using Dijkstra's algorithm

This is an alternative to the minimum cut/maximum flow theorem to find the maximum flow through a network. It seems more intuitive and less error-prone than trying to list all cuts and find the capacity of each one.

Video tutorial showing how to make a program in Scratch that simulates rolling two dice and counting how many times their sum is 8.

This video shows how to take a rule and a transformation and come up with the rule of the image. In the interests of brevity, it only shows how to do it with translations, but the same method can be adapted to other transformations.

A simple introduction to linear programming in under 10 minutes, designed to be suitable for high school students. It includes the "corner point method" and the "sliding line method". The feasible region is the region that is shaded (no mention is made in the video of alternative conventions.)

Tutorial introducing programming in Tickle for the iPad, showing how to program a simulation that rolls two dice and counts how many times the sum is 8.

Given two points, find the rule of a straight line that passes through them both.

Consideration of the unit circle and symmetry to solve trigonometric equations

Based on the Unit Circle, shows how the graphs of sin and cos work.
