In cases like that Wolfram Mathematica is a lifesaver. Wolfram Mathematica basically is a very smart calculator that can not only solve a mathematical problems but also draw graphics and edit pictures.
Firstly, Mathematica’s interface may come as a surprise at first. Entering the program in front of you appears literally a blank sheet that is called notebook. The notebook consists of cells which in turn consist of input and output. The interesting part is how you comment in Mathematica.
