# Python Program to Get Tangent value Using math.tan()

In the previous article, we have discussed Python Program to Reverse each Word in a Sentence
Math Module :

Python’s math module is a built-in module. By importing this module, we can perform mathematical computations.

Numerous mathematical operations like ceil( ),floor( ),factorial( ),mod( ),value of pi ,…..etc .can be computed with the help of math module.

math.tan() Function in Python:

Using this function, we can quickly find the tangent value for a given angle.

Tan is a trigonometric function that represents the Tangent function.
Its value can be calculated by dividing the length of the opposite side by the length of the adjacent side of a right-angled triangle, as we learned in math.

By importing the math module that contains the definition, we will be able to use the tan() function in Python to obtain the tangent value for any given angle.

Examples:

Example1:

Input:

Given lower limit range =0
Given upper limit range =181
Given step size =30

## Program to Get Tangent value using math.tan()

Below are the ways to Get Tangent value.

### Method #1: Using math Module (Static input)

Approach:

• Import math module using the import keyword.
• Give the lower limit range as static input and store it in a variable.
• Give the upper limit range as static input and store it in another variable.
• Give the step size as static input and store it in another variable.
• Loop from lower limit range to upper limit range using For loop.
• Get the angle value in radians from the given range(converting from degree to radians ) and store it in a variable.
• Calculate the Tangent value in a given range for the above-obtained radian values using math.tan() function and store it in another variable.
• print the Tangent Values in the above-given range.
• The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the lower limit range as static input and store it in a variable.
lwer_lmt = 0
# Give the upper limit range as static input and store it in another variable.
upp_lmt = 181
# Give the step size as static input and store it in another variable.
stp_sze = 30
# Loop from lower limit range to upper limit range using For loop.
for vale in range(lwer_lmt, upp_lmt, stp_sze):
# Get the angle value in radians from the given range(converting from degree to radians )
# and store it in a variable.
# Calculate the Tangent value in a given range of above obtained radian values using
# tan()function and store it in another variable.
# print the Tangent Values in the above given range.
print("The Tangent values in a given range are tan(", vale, ') = ', tangt)


Output:

The Tangent values in a given range are tan( 0 ) =  0.0
The Tangent values in a given range are tan( 30 ) =  0.5773502691896257
The Tangent values in a given range are tan( 60 ) =  1.7320508075688767
The Tangent values in a given range are tan( 90 ) =  1.633123935319537e+16
The Tangent values in a given range are tan( 120 ) =  -1.7320508075688783
The Tangent values in a given range are tan( 150 ) =  -0.5773502691896257
The Tangent values in a given range are tan( 180 ) =  -1.2246467991473532e-16

### Method #2: Using math Module (User input)

Approach:

• Import math module using the import keyword.
• Give the lower limit range as User input using the int(input(()) function and store it in a variable.
• Give the upper limit range as User input using the int(input(()) function and store it in another variable.
• Give the step size as User input and store it in another variable.
• Loop from lower limit range to upper limit range using For loop.
• Get the angle value in radians from the given range(converting from degree to radians ) and store it in a variable.
• Calculate the Tangent value in a given range of the above-obtained radian values using the tan()function and store it in another variable.
• print the Tangent Values in the above-given range.
• The Exit of the program.

Below is the implementation:

# Import math module using the import keyword.
import math
# Give the lower limit range as User input using the int(input(()) function and store it in a variable.
lwer_lmt = int(input('Enter some Random number ='))
# Give the upper limit range as User input usingÂ theÂ int(input(())Â function and store it in another variable.
upp_lmt = int(input('Enter some Random number ='))
# Give the step size as User input and store it in another variable.
stp_sze = int(input('Enter some Random number ='))
# Loop from lower limit range to upper limit range using For loop.
for vale in range(lwer_lmt, upp_lmt, stp_sze):
# Get the angle value in radians from the given range(converting from degree to radians )
# and store it in a variable.
# Calculate the Tangent value in a given range of above obtained radian values using
# tan()function and store it in another variable.
# print the Tangent Values in the above given range.
print("The Tangent values in a given range are tan(", vale, ') = ', tangt)


Output:

Enter some Random number = 40
Enter some Random number = 300
Enter some Random number = 45
