Sine of an argument in radians
Syntax
Description
The 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 X
.
Examples
Graph the sine function over the domain .
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 .
