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 .
