what is the plastic ratio? @drpeyam

Uploaded April 2022 | Updated September 2026, 1 week ago

what is the plastic ratio? I define the plastic number and explain its properties, first as a cubic equation and a Fibonacci sequence to count bunnies, then as a fractal cube root with self similarities, and finally a cool formula with hyperbolic cosine function substitution. This is a cool journey through algebra, polynomials, inverse functions, and calculus.

Proof that I did it before mathologer: youtu.be/SMeNVyJjd2o

0:00 Introduction
0:36 Fibonacci
1:45 Fractal
3:10 Hyperbolic trig

$Inhomogeneous case Laplace transform and differential equations We use the Laplace transform to solve differential equations. The good news is that the same technique used to solve homogeneous ODE also works for inhomogeneous differential equations: Take the Laplace transform, solve for it, and then apply the partial fractions technique to find the inverse Laplace transform. This is a must-see for any mathematician, physicist, or engineer, enjoy!
