from sympy import *

# https://certik.github.io/scipy-2013-tutorial/html/index.html#

# Tips:
# 1. SymPy expressions are immutable. No function will change them in-place.
# 2. `simplify` is entirely heuristical and can be unnecessarily slow.
# 3. `factor` is guaranteed to factor the polynomial into irreducible factors.
# 4. if you are only interested in making sure that the expression is in canceled form, `cancel` is more efficient than `factor`.
# 5. by default, SymPy will not perform power simplifications if they are not true in general.
