Sine and hyperbolic sine
Y = sin(X) Y = sinh(X)
sinhcommands 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
Y = sinh(X)returns the hyperbolic sine of the elements of
ExamplesGraph the sine function over the domain and the hyperbolic sine function over the domain
x = -pi:0.01:pi; plot(x,sin(x))The expression
sin(pi)is not exactly zero, but rather a value the size of the floating-point accuracy
piis only a floating-point approximation to the exact value of .
