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.
import math
a = math.pi/6
print ("The value of sine of pi/6 is : ", end="")
print (math.sin(a))
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).
import math
a = math.pi/6
b = 3
c = 4
print ("The value of tangent of pi/6 is : ", end="")
print (math.tan(a))
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.
import math
a = math.pi/6
b = 30
print ("The converted value from radians to degrees is : ", end="")
print (math.degrees(a))
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
