Calculus:<\/strong><\/p>\n

Calculus is a branch of mathematics. Limits, functions, derivatives, integrals, and infinite series are all topics in calculus. To do calculus in Python, we will utilize the SymPy package.<\/p>\n

Derivatives:<\/strong><\/p>\n

How steep is a function at a given point? Derivatives can be used to get the answer to this question. It measures the rate of change of a function at a specific point.<\/p>\n

Integration:<\/strong>
\nwhat is the area beneath the graph over a particular region? Integration can be used to get the answer to this question. It combines the function’s values over a range of numbers.<\/p>\n

SymPy Module:<\/strong><\/h4>\n

SymPy is a Python symbolic mathematics library. It aspires to be a full-featured computer algebra system (CAS) while keeping the code as basic or simple as possible in order to be understandable and easily expandable. SymPy is entirely written in Python.<\/p>\n

Before performing calculus operations install the sympy <\/strong>module as shown below:<\/p>\n

Installation of sympy:<\/strong><\/p>\n

pip install sympy<\/pre>\n

To write any sympy expression, we must first declare its symbolic variables. To accomplish this, we can employ the following two functions:<\/p>\n

sympy.Symbol():<\/strong> This function is used to declare a single variable by passing it as a string into its parameter.<\/p>\n

sympy.symbols():<\/strong> This function is used to declare multivariable by passing the variables as a string as an argument. Each variable must be separated by a space to produce a string.<\/p>\n

1)Limits Calculation in Python<\/h5>\n

Limits are used in calculus to define the continuity, derivatives, and integrals of a function sequence. In Python, we use the following syntax to calculate limits:<\/p>\n

Syntax:<\/strong><\/p>\n

sympy.limit(function,variable,value)<\/pre>\n

For Example:<\/strong><\/p>\n

limit = f(x)<\/strong>
\nx–>k<\/strong><\/p>\n

The parameters specified in the preceding syntax for computing the limit in Python are function, variable, and value.<\/p>\n

f(x):<\/strong> The function on which the limit operation will be conducted is denoted by f(x).
\nx:<\/strong> The function’s variable is x.<\/p>\n

k:<\/strong> k is the value to which the limit tends to.<\/p>\n

Example1: <\/strong>limit y\u2013>0.4= sin(y) \/ y<\/strong><\/p>\n

Approach:<\/strong><\/p>\n
