sin

Sine of argument in radians

Description

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.

  • For real values of X, sin(X) returns real values in the interval [-1, 1].

  • For complex values of X, sin(X) returns complex values.

Plot the sine function over the domain -πxπ.

x = -pi:0.01:pi;
plot(x,sin(x)), grid on

Figure contains an axes object. The axes object contains an object of type line.

Calculate the sine of the complex angles in vector x.

x = [-i pi+i*pi/2 -1+i*4];
y = sin(x)
y = 1×3 complex

Tips

  • To compute sin(X*pi) accurately, without using pi as a floating-point approximation of π, you can use the sinpi function instead. For example, sinpi(n) is exactly zero for integers n and sinpi(m/2) is +1 or –1 for odd integers m.
