In the previous article, we have discussed Python Program for cos() Function
sin() Function in Python:
The sine of a number is returned by the math.sin() method.
The Sine function’s mathematical formula is:
sin(A) = length of opposite side/length of hypotenuse
Syntax:
math.sin(x)
Parameters:
x: This is Required. It is the number to calculate the sine of. If the value is not a number, a TypeError is returned.
Return value:
Returns a float value ranging from -1 to 1 that represents the sine of an angle.
Examples:
Example1:
Input:
Given first number (angle) = 15 Given second number (angle) = 1
Output:
The result after applying sin() function on above given first number 15 = 0.6502878401571168 The result after applying sin() function on above given second number 1 = 0.8414709848078965
Example2:
Input:
Given first number (angle) = 10 Given second number (angle) = 4
Output:
The result after applying sin() function on above given first number 10 = -0.5440211108893698 The result after applying sin() function on above given second number 4 = -0.7568024953079282
Program for sin() Function in Python
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(angle) as static input and store it in another variable.
- Apply math.sin() function to the given first number to get the sine value of a given number (angle).
- Store it in another variable.
- Print the above result.
- Similarly, do the same for the other number.
- Apply math.sin() 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, 2, -0.4, 0.75] # Give the first number (angle) as static input and store it in another variable. gvn_numb1 = 15 # Apply math.sin() function to the given first number to get the sine value # of a given number (angle). # Store it in another variable. fnl_rslt = math.sin(gvn_numb1) print("The result after applying sin() 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 sin() function on above given second number", gvn_numb2, " = ", math.sin(gvn_numb2)) # Apply math.sin() function to the given list element and print it. print( "The result after applying sin() function on given list element gvnlst[1] = ", math.sin(gvn_lst[1]))
Output:
The result after applying sin() function on above given first number 15 = 0.6502878401571168 The result after applying sin() function on above given second number 1 = 0.8414709848078965 The result after applying sin() function on given list element gvnlst[1] = 0.9092974268256817
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 (angle) as user input using the float(input()) function and store it in a variable.
- Apply math.sin() function to the given first number to get the sine value of a given number (angle).
- Store it in another variable.
- Print the above result.
- Similarly, do the same for the other number.
- Apply math.sin() 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(angle) as user input using the float(input()) function # and store it in a variable. gvn_numb1 = float(input("Enter some random number = ")) # Apply math.sin() function to the given first number to get the sine value # of a given number (angle). # Store it in another variable. fnl_rslt = math.sin(gvn_numb1) print("The result after applying sin() 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 sin() function on above given second number", gvn_numb2, " = ", math.sin(gvn_numb2)) # Apply math.sin() function to the given list element and print it. print( "The result after applying sin() function on given list element gvnlst[2] = ", math.sin(gvn_lst[2]))
Output:
Enter some random List Elements separated by spaces = 3 2 6 2 1 Enter some random number = 8 The result after applying sin() function on above given first number 8.0 = 0.9893582466233818 Enter some random number = -5 The result after applying sin() function on above given second number -5.0 = 0.9589242746631385 The result after applying sin() function on given list element gvnlst[2] = -0.27941549819892586
Note: To find the sine of degrees, first convert it to radians using math.radians() method.
For Example:
Approach:
- Import math module using the import keyword.
- Give the first number(angle) as static input and store it in another variable.
- Get the angle in degree by first converting the given angle into radians using math. radians() method and then apply math.sin() method to it.
- Print the given angle in degrees.
- Similarly, do the same for another angle.
- The Exit of Program.
Below is the implementation:
# Import math module using the import keyword. import math # Give the first number(angle) as static input and store it in another variable. gvn_numb1 = 45 # Get the angle in degree by first converting the given angle into radians using # the math. radians() method and then apply math.sin() method to it. angl_in_degre = math.sin(math.radians(gvn_numb1)) # Print the given angle in degrees. print("The sin value of the given angle", gvn_numb1, " in degrees = ", angl_in_degre) # similarly do the same for other angle gvn_numb2 = 60 angl_in_degre = math.sin(math.radians(gvn_numb2)) print("The sin value of the given angle", gvn_numb2, " in degrees = ", angl_in_degre)
Output:
The sin value of the given angle 45 in degrees = 0.7071067811865475 The sin value of the given angle 60 in degrees = 0.8660254037844386
