Python sin () function
description
sin () returns the sine of x radians.
grammar
The following is the syntax sin () method:
import math math.sin(x)
Note: sin () is not directly accessible, you need to import math module, and then call the method by math static objects.
parameter
- x - a value.
return value
Returns the sine of x radians values between -1 and 1.
Examples
The following shows an example of using sin () method:
#!/usr/bin/python import 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)
After running the above example output is:
sin(3) : 0.14112000806 sin(-3) : -0.14112000806 sin(0) : 0.0 sin(math.pi) : 1.22460635382e-16 sin(math.pi/2) : 1
