|MATLAB Function Reference|
sin function operates element-wise on arrays. The function's domains and ranges include complex values. All angles are in radians.
Y = sin(X)
returns the circular sine of the elements of
Graph the sine function over the domain .
sin(pi) is not exactly zero, but rather a value the size of the floating-point accuracy
pi is only a floating-point approximation to the exact value of .
The sine can be defined as
