Drawing the Graphs of Functions and Data Using Mathematica

Mathematica is a software system of the sign calculating,providing the varieties of mathematical tools for the researchers also conveniently verifying the calculations in the thesis.Besides,much information will be achieved by drawing the graphs in Mathematica which is also a good assistant that the students′parents check children′s homework.Furthermore,the graphs of functions and data will be drawn using the several simple commands of Mathematica if the data or functions are given,which is one the of Mathematica′s features.
