Python – math.asin() function
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.
Below examples illustrate the use of above function:
Example 1:
# 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:
# Python code to implement# the aasin()functionimport 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]
