sin, sinh

Sine and hyperbolic sine

Syntax

Y = sin(X)
Y = sinh(X)

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

x = -pi:0.01:pi; plot(x,sin(x))



x = -5:0.01:5; plot(x,sinh(x))

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 .
