2. Create a function that, given a basis B and a vector [x]B, computes the vector x. Use functions from numpy, scipy, and/or sympy. Create a function comment header that summarizes your approach. In the same file, compute the the vector x given B and [x]B below and print the result. Save your code as problem2.py.
