Speaking of accademic, anyone have a Java implementation of tanh(x)? The
java.lang.Math class only has tan(x) or atan(x), but no hyperbolic function.
Trivial, see http://functions.wolfram.com/ElementaryFunctions/Tanh/02/ (yeah, wolfram research is for mathematics on the net what wikipedia is for the rest)
double tanh(double x) {
return (Math.exp(x)-Math.exp(-x))/(Math.exp(x)+Math.exp(-x));
}Have fun!
