0. Do you know any equation for the curve below?
Hyperbolic Functions
1. Review
Any function f(x) with a symmetrical domain can be represented as the sum of an even function and an odd function
Review part
2.Explain the definitions of sin(x) and cosh(x)
Why are they called sinh(x) and cosh(x), instead of “ccsch” or “sinp” ?
2.1 Why “sin/cos” here?
2.1.2 similar properties？
2.2 why is there a “h” here?
answers
hyperbola:双曲线
Check with GeoGebra: Parametrical hyperbola
3.Find the graphs of cosh(x) and sinh(x) with GeoGebra
using graphs.ggb
4.Catenary: application of cosh(x) in real life
