Weird, funky types of distance can still be thought of as "distance", but what actually is distance anyways? In this video we are going to introduce the big ideas of Metric Spaces. A Metric Space tries to generalize the notion of distance that we are all familiar with: straight line or Euclidean distance. We will see a couple other types of of distance such as the Manhattan distance aka the taxicab metric, as well as the Chebyshev distance which is basically how the king moves in chess. All of these are actually metrices! So what is a metric? Well it is a way of associating a distance that obeys three properties:
1) d(A,B)=0 iff A=B
2) d(A,B)=d(B,A) ie a symmetry property
3) d(A,C) less than or equal to d(A,B)+d(B,C), called the triangle inequality.
Metric spaces are a foundational idea in the field of mathematical analysis.
