Consider now a problem of transforming the diamond back into square. This is achieved by the inverse transform. QUESTION 3a: (8 pts) Use the function in to find the inverse of the transformation and store it as P_inv. (Hint: you can use to join two 33 matrices into one 36 matrix.) Recall that, if we do Gauss-Jordan process on [PI3] where I3 is the 33 identity matrix, then at the end we get [I3P1] Note: Call to round to in your final answer, if P is a \#\#Edit this cell to answer the question. You only need to find P_inv using the above method, your \( P_{\text {_ }} \) inv P_inv =0 \# P_inv is sympy.matrix \# keep these two lines for answer checking P_inv_round = P_inv.eval f(2) print(P_inv_round)
