Hyperbolic Functions. The two basic hyperbolic functions are: sinh and cosh. (pronounced "shine" and "cosh") sinh x = ex − e−x 2.
Keeping this in consideration, what does Cosh and Sinh mean?
If, instead of a circle, we do the same thing for a hyperbola defined x^2-y^2=1, you get the x and y values called cosh and sinh, with cosh^2 (x)-sinh ^2 (x)=1. The circular trig functions sin and cos are defined as a parameterization of the unit circle (radius 1) defined by x^2+y^2=1.
Thereof, what is Sinh?
Sinh is the hyperbolic sine function, which is the hyperbolic analogue of the Sin circular function used throughout trigonometry. It is defined for real numbers by letting be twice the area between the axis and a ray through the origin intersecting the unit hyperbola . Sinh threads element-wise over lists and matrices.
Calculates the hyperbolic cosine of a value. The hyperbolic trig functions sinh(, cosh(, and tanh( are an analog of normal trig functions, but for a hyperbola, rather than a circle. They can be expressed in terms of real powers of e, and don't depend on the Degree or Radian mode setting.
