What is an Injective Function? Definition and Explanation
An explanation to help understand what it means for a function to be injective, also known as one-to-one. The definition of an injection leads us to some important properties of injective functions! Subscribe to see more new math videos! Music: OcularNebula - The Lopez

Definition of an Injective Function and Sample Proof
We define what it means for a function to be injective and do a simple proof where we show a specific function is injective. Injective functions are also called one-to-one functions. Useful Math Supplies https://amzn.to/3Y5TGcv My Recording Gear https://amzn.to/3BFvcxp (these are my affil

Laser: Static Analysis for Ruby, in Ruby by Michael Edgar
What truly makes Ruby special as a language is its focus on expressivity, flexibility, and dynamism. Yet these same properties - and their widespread use in the community - make even straightforward application code difficult to analyze statically in a meaningful way. Laser seeks to change
