Differentiator

Differentiation of any expressions and subsequent analysis.

Installing

Project supported on Linux only.
Differentiator requires pdfTeX.
To start clone repository and make project: > make main

Features

• Supporting of many variables.
• Supporting exponential function(^), sin, cos, ln and tg. Also supported Euler's number.
• Differentiator creates article (Derivate.pdf) in scientific-like style.
• Plots of the original function and derivate function (if expression contains one variable).
• Simplification of the expressions.
• All the steps of differentiation and simplification are reflected in the article.

Usage

Grammar of expression

{} - optional
[] - obligatory
{}*, []* - repeat ({}* could be 0 times)

• Variable: set of latin letters, except of e(Reserved - Euler's number).
• Number: any rational number
• Function: sin(Expression) | cos(Expression) | ln(Expression) | tg(Expression)
• Priority: (Expression) | Number | Variable | Function
• Unary: {+ | -} Priority
• Power: Unary{^ Unary}*
• Term: Power{[* | \] Power}*
• Expression: Term {[+ | -] Term}*
• Global: Expression '\0'

Program launch

1. Create expression.txt file and put there math expression.
2. Do ./differentiator
3. Derivate.pdf is done, you can enjoy
