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
# 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
# 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
# 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
