Solve a set of coupled ODEs taken from Lorenz's book, "The Essence of Chaos", to describe the motion of a frictionless board as it moves down an infinite-sloped surface of sinusoidal humps
Exhibit relevancy for many industries, specifically in academia
Perform ordinary differential equations (ODEs), RKadapt, and Runge Kutta 4th order solvers with adaptive time step
This worksheet sets up a set of coupled ordinary differential equations. A matrix of the functions for the x/y positions and velocities is defined. It's then passed to the RKadapt function. The x/y positions are plotted with a 3D plot of the sinusoidal humps, marking the trajectory of the board as it travels through the humps. In practical terms, this can be thought of as the motion of a set of skis going down a mountain. Step by step notation, formulas, equations, graphs, images, and solutions are all provided in this worksheet to aid you.
