Python Program for tan() Function

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

The tangent of a number is returned by the math.tan() method.

The tangent function’s mathematical formula is:

tan(A) = length of opposite side/length of adjacent side

Syntax:

math.tan(x)

Parameters:

x: This is Required. It is the number to calculate the tangent of. If the value is not a number, a TypeError is returned.

Return Value:

Returns a float value representing a number’s tangent.

  • The tan function returns the Tangent value if the number argument is positive or negative.
  • The tan function returns TypeError if the number argument is not a number.

Examples:

Example1:

Input:

Given first number (angle) = 60
Given second number (angle) = 45

Output:

The result after applying tan() function on above given first number 60  =  0.320040389379563
The result after applying tan() function on above given second number 45  =  1.6197751905438615

Example2:

Input:

Given first number (angle) = 90
Given second number (angle) = 15

Output:

The result after applying tan() function on above given first number 90  =  -1.995200412208242
The result after applying tan() function on above given second number 15  =  -0.8559934009085187

Program for tan() 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.tan() function to the given first number to get the tangent value of a given number (angle).
  • Store it in another variable.
  • Similarly, do the same for the other number.
  • Apply math.tan() 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 = [5, 15, 6, 7]
# Give the first number (angle) as static input and store it in another variable.
gvn_numb1 = 60
# Apply math.tan() function to the given first number to get the tangent value
# of a given number (angle).
# Store it in another variable.
fnl_rslt = math.tan(gvn_numb1)
print("The result after applying tan() function on above given first number",
      gvn_numb1, " = ", fnl_rslt)
# similarly do the same for the other number.
gvn_numb2 = 45
print("The result after applying tan() function on above given second number",
      gvn_numb2, " = ", math.tan(gvn_numb2))
# Apply math.tan() function to the given list element and print it.
print(
    "The result after applying tan() function on given list element gvnlst[1] = ", math.tan(gvn_lst[1]))

Output:

The result after applying tan() function on above given first number 60  =  0.320040389379563
The result after applying tan() function on above given second number 45  =  1.6197751905438615
The result after applying tan() function on given list element gvnlst[1] =  -0.8559934009085187

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.tan() function to the given first number to get the tangent value of a given number (angle).
  • Store it in another variable.
  • Similarly, do the same for the other number.
  • Apply math.tan() 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.tan() function to the given first number to get the tangent value
# of a given number (angle).
# Store it in another variable.
fnl_rslt = math.tan(gvn_numb1)
print("The result after applying tan() 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 tan() function on above given second number",
      gvn_numb2, " = ", math.tan(gvn_numb2))
# Apply math.tan() function to the given list element and print it.
print(
    "The result after applying tan() function on given list element gvnlst[2] = ", math.tan(gvn_lst[2]))

Output:

Enter some random List Elements separated by spaces = 10 20 30 40 50
Enter some random number = 90
The result after applying tan() function on above given first number 90.0 = -1.995200412208242
Enter some random number = 65
The result after applying tan() function on above given second number 65.0 = -1.4700382576631723
The result after applying tan() function on given list element gvnlst[2] = -6.405331196646276
