One can use computer algebra systems to solve such equations. In this section, the use of various systems will be discussed. The intent here is to give a reasonably simple way to obtain these solutions, not to give all possible ways to use these systems. In this book, I will be emphasizing MATLAB. However, other systems will be discussed in this section. One very easy to use system which behaves a lot like MATLAB is Scientific Notebook, which is actually based on mupad. I will mention its use also.
