# Python3.x Python3 sin() Function [ Python3 Numbers](#) * * * ## Description **sin()** returns the sine of x radians. * * * ## Syntax Here is the syntax for the sin() method: import math math.sin(x) **Note:** sin() cannot be accessed directly; you need to import the math module and then call the method via the math static object. * * * ## Parameters * x -- A numeric value. * * * ## Return Value Returns the sine of x radians, with a value between -1 and 1. * * * ## Example The following example demonstrates the use of the sin() method: #!/usr/bin/python3import math print ("sin(3) : ", math.sin(3))print ("sin(-3) : ", math.sin(-3))print ("sin(0) : ", math.sin(0))print ("sin(math.pi) : ", math.sin(math.pi))print ("sin(math.pi/2) : ", math.sin(math.pi/2)) When the above example is run, it produces the following result: sin(3) : 0.1411200080598672 sin(-3) : -0.1411200080598672 sin(0) : 0.0 sin(math.pi) : 1.2246467991473532e-16 sin(math.pi/2) : 1.0 [ Python3 Numbers](#)
