## Symbolic math and python

With the help of python and SymPy module one can do pretty neat computations. For example when I took a course about Robotic Preception on Coursera I had to find a cross product of two vectors v1 x v2 represented in a generic form: v1 = (a, b, c) v2 = (d, e, 0) Normally I would write it down on a piece of paper and do the computations myself. Luckily python can help with that....
