Introduction Python math.sin() Method with Examples

math.sin() method is a library method of math module, it is used to get the sine of the number in radians, it accepts a number returns the cosine of the given number in radians.

Python math.sin()

Syntax

math.sin(x)

Parameter(s):

• It takes one parameter x, which takes values of the numeric datatype and throws TypeError if an argument is of any other data type is passed.

Return Value

• float – it returns a float value that is the sine value of the number x radians.

Examples of Python math.sin() method

Example 1

a = 0.278

# function call
print(math.sin(a))

Output

0.27443298625778634

Example 2

Write a program to show the working of sin() method in Python.

import math

a1 = 0.36
b1 = 1
c1 = -1
d1 = -0.36

print("Value for parameter ", a1, " is ", math.sin(a1))
print("Value for parameter ", b1, " is ", math.sin(b1))
print("Value for parameter ", c1, " is ", math.sin(c1))
print("Value for parameter ", d1, " is ", math.sin(d1))

Output

Value for parameter  0.36  is  0.35227423327508994
Value for parameter  1  is  0.8414709848078965
Value for parameter  -1  is  -0.8414709848078965
Value for parameter  -0.36  is  -0.35227423327508994

Example 3

Write a program to pass the value out of range from the sin() function and display the output.

import math

a = 'Hello'
print(math.cos(a))

Output

For output:   TypeError: must be real number, not str

In this example, we’ve seen that passing a parameter, which is not a real number, throws a TypeError.

Python sin() function is used to find the sine of a given argument in radians. Where sine is a trigonometric function which represents the ratio between hypotenuse and opposite.
