commands → sinh

sinh(x)

The sinh command computes the hyperbolic sine of x where x is in radians. If x is a floating point number then a floating point result is computed, otherwise the result is an exact symbolic value.

Examples 

# hardware floating point
sinh(1.0);
	1.1752011936438

# symbolic
sinh(1);
	sinh(1)

Algorithm

To compute sinh(x) in extended precision we compute its power series.
