Python Program for asin() Function

In the previous article, we have discussed Python Program for acos() Function
asin() Function in Python:

The arc sine of a number is returned by the math.asin() method.

Note: It should be noted that the parameter passed in math.asin() must be between -1 and 1.

Tip: math.asin(1) returns the value PI/2, while math.asin(-1) returns the value -PI/2. (where PI= 22/7)

Syntax:

math.asin(x)

Parameters:

x: This is required. It is a number between -1 and 1. If x is not a number, a TypeError is returned.

Return Value:

Returns a float value which represents a number’s arc sine.

The asin() function returns the Arc Sine value if the number argument is positive or negative.
The asin() function returns TypeError if it is not a number.
If it is not between -1 and 1, the asin() function returns ValueError.

Examples:

Example1:

Input:

Given first number =  0.5
Given second number = 1

Output:

The result after applying asin() function on above given first number 0.5  =  0.5235987755982989
The result after applying asin() function on above given second number 1  =  1.5707963267948966

Example2:

Input:

Given first number = -1
Given second number =  0.6

Output:

The result after applying asin() function on above given first number -1  =  -1.5707963267948966
The result after applying asin() function on above given second number 0.6  =  0.6435011087932844

Method #1: Using Built-in Functions (Static Input)

Approach:

Import math module using the import keyword.
Give the list as static input and store it in a variable.
Give the first number as static input and store it in another variable.
Apply math.asin() function to the given first number to get the arc sine value (inverse of sine) of a given number.
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.asin() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as static input and store it in a variable.
gvn_lst = [0.92, 0.1, -0.4, 0.75]
# Give the first number as static input and store it in another variable.
gvn_numb1 = 0.5
# Apply math.asin() function to the given first number to get arc sine value
# (inverse of sine) of a given number.
# Store it in another variable.
fnl_rslt = math.asin(gvn_numb1)
print("The result after applying asin() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = 1
print("The result after applying asin() function on above given second number",
      gvn_numb2, " = ", math.asin(gvn_numb2))
# Apply math.asin() function to the given list element and print it.
print(
    "The result after applying asin() function on given list element gvnlst[1] = ", math.asin(gvn_lst[1]))

Output:

The result after applying asin() function on above given first number 0.5  =  0.5235987755982989
The result after applying asin() function on above given second number 1  =  1.5707963267948966
The result after applying asin() function on given list element gvnlst[1] =  0.1001674211615598

Method #2: Using Built-in Functions (User Input)

Approach:

Import math module using the import keyword.
Give the list as user input using list(),map(),input(),and split() functions.
Store it in a variable.
Give the first number as user input using the float(input()) function and store it in a variable.
Apply math.asin() function to the given first number to get the arc sine value (inverse of sine) of a given number.
Store it in another variable.
Print the above result.
Similarly, do the same for the other number.
Apply math.asin() function to the given list element and print it.
The Exit of Program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the list as user input using list(),map(),input(),and split() functions.
# Store it in a variable.
gvn_lst = list(map(float, input(
    'Enter some random List Elements separated by spaces = ').split()))
# Give the first number as user input using the float(input()) function
# and store it in a variable.
gvn_numb1 = float(input("Enter some random number = "))
# Apply math.asin() function to the given first number to get arc sine value
# (inverse of sine) of a given number.
# Store it in another variable.
fnl_rslt = math.asin(gvn_numb1)
print("The result after applying asin() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = float(input("Enter some random number = "))
print("The result after applying asin() function on above given second number",
      gvn_numb2, " = ", math.asin(gvn_numb2))
# Apply math.asin() function to the given list element and print it.
print(
    "The result after applying asin() function on given list element gvnlst[2] = ", math.asin(gvn_lst[2]))

Output:

Enter some random List Elements separated by spaces = 0 3 -0.5 3 -1
Enter some random number = -1
The result after applying asin() function on above given first number -1.0 = -1.5707963267948966
Enter some random number = 0.6
The result after applying asin() function on above given second number 0.6 = 0.6435011087932844
The result after applying asin() function on given list element gvnlst[2] = -0.5235987755982989
