Combinations

A Combination is any unordered subset of a larger set “S” (a bit different from a Permutation, innit?) So if S={1,2,3}, then {1,2}={2,1} as order don′t count… Read more “Combinations”

Permutations

A Permutation of a larger set “S” of n objects is any ordered subset of that set. The total number of permutations of r objects from n… Read more “Permutations”

The Multiplication Principle

A long time ago (last month) in a land far, far away (from wherever the hell I come from) there was a math module craftily named “Methods… Read more “The Multiplication Principle”

Vectors

What is a vector? Well, what most physics students in high-school learn about is that they are mathematical objects that have both “magnitude and direction”, i.e. they’re… Read more “Vectors”

Algebra

What is Algebra? I asked my friend what she thinks, and she said “It’s an area of math, and it deals with numbers.” Not wrong! As I… Read more “Algebra”

Vector Analysis

As far as I can tell ya (and I can’t really tell, since I’m still reading) Vector Analysis is all about a calculus involving vectors and their… Read more “Vector Analysis”

The Section Formula

A fairly simple result involving Vectors, more often than not misconstrued as something difficult to understand (like most Mathematics these days is…). It’s super duper simple, but… Read more “The Section Formula”
