Sine and hyperbolic sine

Syntax

Description

The sin and sinh commands operate element-wise on arrays. The functions' domains and ranges include complex values. All angles are in radians.

Y = sin(X) returns the circular sine of the elements of X.

Y = sinh(X) returns the hyperbolic sine of the elements of X.

Examples

Graph the sine function over the domain and the hyperbolic sine function over the domain

The expression sin(pi) is not exactly zero, but rather a value the size of the floating-point accuracy eps, because pi is only a floating-point approximation to the exact value of .
