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

Some of the mathematical functions are discussed in below set 1 and set 2

Mathematical 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 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).

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.
