Math Functions in Python | Set 3 (trigonometric and angle functions)

Math functions in Python | Set 2 (logarithmic and power functions)

Trigonometric and angle functions are discussed in this article.

1. sin () : — This function returns the sine of the value passed as an argument. The value passed to this function must be in radians .

2. cos () : — This function returns the cosine of the value passed as an argument. The value passed to this function must be in radians .

# Python code to demonstrate how it works # sin () and cos ()   # import math for math operations import math   a = math.pi / 6   # returns sine pi / 6 print ( "The value of sine of pi / 6 is:" , end = "") print (math.sin (a))   # returns cosine pi / 6 value 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 the value passed as an argument. The value passed to this function must be in radians .

4. hypot (a, b) : — returns the hypotenuse of the values ​​passed in the arguments. Returns numerically sqrt (a * a + b * b) .

# Python code to demonstrate how it works # tan () and hypot ()   # import math for math operations import math   a = math.pi / 6 b = 3 c = 4   # returning the tangent of pi / 6 print ( "The value of tangent of pi / 6 is:" , end = "") print (math. tan (a))   # returns hypotenuse 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 the argument value from radians to degrees .

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

# Python code to demonstrate how it works # degrees () and radians ()   # import math for math operations import math   a = math.pi / 6 b = 30   # returns the converted value from radians to degrees print ( " The converted value from radians to degrees is: " , end = " ") print (math.degrees (a))   # returns 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
