Python TAN Function

Python tan

by

The Python tan math function calculates the Trigonometry Tangent for the specified expression. In this section, we show how to use the tan function in Python Programming language with example.

The mathematical formula behind the Python Trigonometry Tangent function is

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

Python tan Function Syntax

The syntax of the tan Function is

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

Python tan Function Example

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

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

# 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'))
Python TAN Function

First, we declared Python List and Tuple with some random values. Next, we used the tan Function on both the Positive integer and negative integer. The following statements 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 see the above screenshot, the tan function is works 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 Math function on multiple values.

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

Within the last statement, we tried the tan Function on the String value, and it returns TypeError as output.

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