Y = sin(X) Y = sinh(X)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
.
Graph the 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 asin
