Python math.sin() Method

❮ Math Methods

Example

Find the sine of different numbers:

# Import math Library
import math

# Return the sine of different values
print (math.sin(0.00))
print (math.sin(-1.23))
print (math.sin(10))
print (math.sin(math.pi))
print (math.sin(math.pi/2))

Definition and Usage

The math.sin() method returns the sine of a number.

Note: To find the sine of degrees, it must first be converted into radians with the math.radians() method (see example below).

Syntax

math.sin(x)

Parameter Values

Parameter Description
x Required. The number to find the sine of. If the value is not a number, it returns a TypeError

Technical Details

Return Value: A float value, from -1 to 1, representing the sine of an angle
Python Version: 1.4

More Examples

Example

Find the sine of different degrees:

# Import math Library
import math

# Return the sine value of 30 degrees
print(math.sin(math.radians(30)))

# Return the sine value of 90 degrees
print(math.sin(math.radians(90)))
