What is math.sin() in Python?
The sin() function returns a
The illustration below shows the mathematical representation of the sin() function.
Note:
- The
mathmodule is required for this function.- This
sin()function only works for right-angled triangles.
Syntax
sin(num)
Parameter
This function requires a number that represents an angle in radians as a parameter.
In order to convert degrees to radians, use the following formula:
radians = degrees * ( pi / 180.0 )
Return value
sin() returns the sine of a number (in radians) that is sent as a parameter. The return value is in the range [-1,1].
Code
import math#positive number in radiansprint "The value of sin(2.3) : ", math.sin(2.3)#negative number in radiansprint "The value of sin(-2.3) : ", math.sin(-2.3)#converting the degrees angle into radians and then applying sin()#degrees = 90#PI = 3.14159265result = 90.0 * (math.pi / 180.0)print "The value of sin("+str(result)+") : ", math.sin(result)
