sine 40° = 0.642788
The sine of 75 degrees is about 0.9659
In all there are [at least] 24 trigonometric functions and ratios. Half of these are circular and the other half are hyperbolic. Sine and Cosine are basic trigonometric funtions, abbreviated as sin and cos. Tangent is the third basic ratio defined as Sin/Cos. For each of these three, there is a corresponding reciprocal function: Sine -> Cosecant (cosec or csc) Cosine -> Secant (sec) Tangent -> Cotangent (cot). Each of the above six has an inverse function, defined on an appropriate domain. They all are named by adding the prefix "arc", for example arcsin, which is usually written as sin-1. The above are the circular functions. Each one of them has a corresponding hyperbolic equivalent. These are named by adding the suffix, "h", thus cosh, sech, arccosh [= cosh-1], etc.
Sine Pari is Latin for "without equal".
-1 < sine(theta) < 1 so sine(theta) cannot be 3125

∫ sinh(x) dx = cosh(x) + C C is the constant of integration.
∫ 1/sinh2(x) dx = -cotanh + C C is the constant of integration.
∫ 1/sinh(x) dx = ln(tanh(x/2)) + C C is the constant of integration.
The equation of a hyperbolic function is y = sinh(x) or y = cosh(x), where sinh(x) represents the hyperbolic sine function and cosh(x) represents the hyperbolic cosine function. Hyperbolic functions are similar to trigonometric functions but are defined in terms of exponentials.
An arc-hyperbolic function is an inverse hyperbolic function.
It works in Euclidean geometry, but not in hyperbolic.
Journal of Hyperbolic Differential Equations was created in 2004.
by creating two planes such that one parallel is hyperbolic and the other parabolic
It is a hyperbolic function.
