Sine of argument in radians
Y = sin(X)
example
Y = sin(X) returns the sine of the elements of X. The sin function operates element-wise on arrays. The function accepts both real and complex inputs.
Y
X
sin
For real values of X, sin(X) returns real values in the interval [-1, 1].
sin(X)
For complex values of X, sin(X) returns complex values.

Sine of input angle, returned as a real-valued or complex-valued scalar, vector, matrix or multidimensional array.
The sine of an angle, α, defined with reference to a right triangle is
sin(α)=opposite sidehypotenuse=ah .
The sine of a complex argument, α, is
sin(α)=eiα−e−iα2i .
