Hyperbolic Functions - tanh(x), sinh(x), cosh(x) - Introduction

in hive-196037 •  2 years ago  (edited)


In this video I introduce what hyperbolic functions are and show how they relate to the hyperbola (and hence their name is derived) in the same way that trigonometric functions relate to the circle. I also derive the identity cosh2(x) - sinh2(x) = 1.

I don't always go over hyperbolic functions but when I do I usually show how they get their name from the hyperbola ;)
