Math for Liberal Studies - Lecture 3.6.2 The Bifid Cipher
This is the second video lecture for Math for Liberal Studies Section 3.6: An Introduction to Cryptography. In this lecture, we discuss a new method for encrypting and decrypting messages: the bifid cipher. This method relies on converting the letters in the message to coordinates in a let

What is a Bipartite Graph? | Graph Theory
What is a bipartite graph? We go over it in today’s lesson! I find all of these different types of graphs very interesting, so I hope you will enjoy this lesson. A bipartite graph is any graph whose vertex set can be partitioned into two disjoint sets (called partite sets), such that all e

Math for Liberal Studies - Lecture 3.7.2 The Vigenère and Autokey Ciphers
This is the second video for Math for Liberal Studies Section 3.7: Modular Arithmetic and Ciphers. In this video, we apply the modular arithmetic ideas from the previous lecture to cryptography. Specifically, we learn how to replace the letters in a message with numbers and perform "letter

Solving a trig function with sine and cosine
👉 Learn how to solve trigonometric equations. There are various methods that can be used to evaluate trigonometric equations, they include factoring out the GCF and simplifying the factored equation. Another method is to use a trigonometric identity to reduce and then simplify the given eq

Isolating a logarithm and using the power rule to solve
👉 Learn how to solve logarithmic equations. Logarithmic equations are equations with logarithms in them. To solve a logarithmic equation, we first isolate the logarithm part of the equation. After we have isolated the logarithm part of the equation, we then get rid of the logarithm. This i

Row and column polynumbers | Arithmetic and Geometry Math Foundations 65 | N J Wildberger
This video introduces a two-dimensional aspect to arithmetic by considering both polynumbers written as columns and as rows, and then putting those two ideas together to define bipolynumbers, whose coefficients form a rectangle. The associated polynomials are written in two variables, alph

What are Complete Bipartite Graphs? | Graph Theory, Bipartite Graphs
What are complete bipartite graphs? We'll define complete bipartite graphs and show some examples and non-examples in today's video graph theory lesson! Remember a graph G = (V, E) is bipartite if the vertex set V can be partitioned into two sets V1 and V2 (called partite sets) such that
