plotgraf(varargin)

function varargout = plotgraf(varargin)
% Simple graphic calculator allows to perform the following:
% 
% Draw functions.
% Develop the Taylor series function.
% Integrate the given function.
% Derive the function.
% Simplify the mathematical expressions.
% 
% Using the calculator is simple: to enter the function if we would like to draw the function, press Enter.
% To perform any of the above mentioned
% Enter the function and click the appropriate button
