pyculas

Installation Instructions

use pip or pip3 to install the library.

pip install pyculas

Note:

Currently this library support only algebraic expressions. Soon we will update for trigonometric, logarithmic expressions , etc.

Usage

This class takes a list of terms in a polynomial expression

Importing

from pyculas import Expression

Examples of usage:

If you have 4x^3 - 2x + 6, then create the object as follows -

A = Expression.algebraic("4x^3 - 2x + 6")

This method differentiates a polynomial expression at a given value and outputs the final expression.

Output:

('12x^2 - 2' , None)

1.If only final expression required

Q. 2x^2+2

A = Expression.algebraic("2x^2 + 2")
print(A.differentiate())

Output:

('4x' , None)

2.To get value at a point

Q. Find the differentiation of 2x^2+2 at x=3.

A = Expression.algebraic("2x^2 + 2")
print(A.differentiate(value=3,level=1))

Output:

('4x' , 12)

Here value means at which point you want to differentiate and level means the nth derivative.
