Math module contains a number of functions which is used for mathematical operations. The math.asin() function returns the arc sine value of a number. The value passed in this function should be between -1 to 1.
Syntax: math.asin(x) Parameter:This method accepts only single parameters.
- x :This parameter is the value to be passed to asin()
Returns:This function returns the arc sine value of a number.
Time Complexity: O(1)
Auxiliary Space: O(1)
Below examples illustrate the use of above function: Example 1:
Python3
# Python code to implement # the acos()function # importing "math" # for mathematical operations import math a = math.pi / 6 # returning the value of arc sine of pi / 6 print ( "The value of arc sine of pi / 6 is : " , end = "") print (math.asin(a)) |
Output:
The value of arc sine of pi / 6 is : 0.5510695830994463
Example 2:
Python3
# Python code to implement # the aasin()function import math import matplotlib.pyplot as plt in_array = [ - 0.14159265 , - 0.57039399 , - 0.28559933 , 0.28559933 , 0.57039399 , 0.94159265 ] out_array = [] for i in range ( len (in_array)): out_array.append(math.asin(in_array[i])) i + = 1 print ( "Input_Array : \n" , in_array) print ( "\nOutput_Array : \n" , out_array) plt.plot(in_array, out_array, "go:" ) plt.title( "math.asin()" ) plt.xlabel( "X" ) plt.ylabel( "Y" ) plt.show() |
Output:
Input_Array : [-0.14159265, -0.57039399, -0.28559933, 0.28559933, 0.57039399, 0.94159265] Output_Array : [-0.14207008957392517, -0.6069854488522558, -0.2896317474780172, 0.2896317474780172, 0.6069854488522558, 1.227328875116741]
