Python TAN

by

The Python TAN function is one of the Python Math function which is used to calculate the Trigonometry Tangent for the specified expression. In this article we will show you, How to use TAN() function in Python Programming language with example.

The mathematical formula behind the Trigonometry Tangent function is as shown below:

TAN(x) = Length of the Opposite Side / Length of the Adjacent Side

TIP: Please refer Python ATAN Function article to find the Arc Tangent of specified expression.

Syntax of a Python TAN Function

The basic syntax of the TAN Function in Python Programming Language is as shown below:

Math.tan(number);

Number: It can be a number or a valid numerical expression for which you want to find Tangent value.

  • If the number argument is positive or negative number, tan() function will return the Tangent value.
  • If the number argument is not a number, tan() function will return TypeError.

Python TAN Function Example

The Python TAN Function allows you to find the trigonometry Tangent for the numeric values. In this example, We are going to find the Tangent values of different data types and display the output

PYTHON CODE

# Python TAN Function

import math

Tup = (1, 2, 3, -4 , 5)
Lis = [-1, 2, -3.5, -4 , 5]

print('Tangent value of Positive Number = %.2f' %math.tan(10))
print('Tangent value of Negative Number = %.2f' %math.tan(-15))

print('Tangent value of Tuple Item = %.2f' %math.tan(Tup[3]))
print('Tangent value of List Item = %.2f' %math.tan(Lis[2]))

print('Tangent value of Multiple Number = %.2f' %math.tan(10 + 20 - 40))

print('Tangent value of String Number = ', math.tan('Hello'))

OUTPUT

Python TAN Function

ANALYSIS

First, We declared Python List and Tuple with some random values. Next, We used the TAN() Function directly on both the Positive integer and negative integer. Following statements will find the Tangent of the corresponding values.

print('Tangent value of Positive Number = %.2f' %math.tan(10))
print('Tangent value of Negative Number = %.2f' %math.tan(-15))

Next, We used the TAN() Function on Python Tuple and List items. If you observe the above screenshot, TAN() function is working perfectly on them.

print('Tangent value of Tuple Item = %.2f' %math.tan(Tup[3]))
print('Tangent value of List Item = %.2f' %math.tan(Lis[2]))

Next, We used the TAN() Function directly on multiple values.

print('Tangent value of Multiple Number = %.2f' %math.tan(10 + 20 - 40))

Within the last statement, We tried TAN() Function on String value. As we said before, this will return TypeError as output

print('Tangent value of String Number = ', math.tan('Hello'))
