How to Understand Dot Product and Cross-Product
The dot product outputs a scalar and captures the angle between two vectors. The cross product outputs a vector, which is perpendicular to the plane of the two input vectors and captures both the angle between the vectors and the plane in which they lie.Both operations are foundational in physics, engineering, and computer science, especially […]
An In-depth Exploration of How to Find the Codomain
TL;DR: Think of the codomain as a function’s official invite list — every value you said the outputs are allowed to come from. The range, on the other hand, is the guest list that actually shows up. For a function from the real numbers to the real numbers, the codomain is every real number, but […]
