Mathematical Functions in Python | Set 3 (Trigonometric and Angular Functions) (original) (raw)

Last Updated : 28 Jul, 2016

Some of the mathematical functions are discussed in below set 1 and set 2Mathematical Functions in Python | Set 1 (Numeric Functions) Mathematical Functions in Python | Set 2 (Logarithmic and Power Functions)Trigonometric and angular functions are discussed in this article.1. sin() :- This function returns the sine of value passed as argument. The value passed in this function should be in radians. 2. cos() :- This function returns the cosine of value passed as argument. The value passed in this function should be in radians.

Python `

Python code to demonstrate the working of

sin() and cos()

importing "math" for mathematical operations

import math

a = math.pi/6

returning the value of sine of pi/6

print ("The value of sine of pi/6 is : ", end="") print (math.sin(a))

returning the value of cosine of pi/6

print ("The value of cosine of pi/6 is : ", end="") print (math.cos(a))

`

Output:

The value of sine of pi/6 is : 0.49999999999999994 The value of cosine of pi/6 is : 0.8660254037844387

3. tan() :- This function returns the tangent of value passed as argument. The value passed in this function should be in radians. 4. hypot(a, b) :- This returns the hypotenuse of the values passed in arguments. Numerically, it returns the value of sqrt(a*a + b*b).

Python code to demonstrate the working of

tan() and hypot()

importing "math" for mathematical operations

import math

a = math.pi/6 b = 3 c = 4

returning the value of tangent of pi/6

print ("The value of tangent of pi/6 is : ", end="") print (math.tan(a))

returning the value of hypotenuse of 3 and 4

print ("The value of hypotenuse of 3 and 4 is : ", end="") print (math.hypot(b,c))

`

Output:

The value of tangent of pi/6 is : 0.5773502691896257 The value of hypotenuse of 3 and 4 is : 5.0

5. degrees() :- This function is used to convert argument value from radians to degrees.6. radians() :- This function is used to convert argument value from degrees to radians.

Python code to demonstrate the working of

degrees() and radians()

importing "math" for mathematical operations

import math

a = math.pi/6 b = 30

returning the converted value from radians to degrees

print ("The converted value from radians to degrees is : ", end="") print (math.degrees(a))

returning the converted value from degrees to radians

print ("The converted value from degrees to radians is : ", end="") print (math.radians(b))

`

Output:

The converted value from radians to degrees is : 29.999999999999996 The converted value from degrees to radians is : 0.5235987755982988
