Problem 2: Determinants

write code in python, sagemath

Grading criteria: correctness of code and explanations.

2a. Implement a function called my_det that calculates the determinant of a matrix recursively using expansion by cofactors. The Matrix methods delete_columns and delete_rows may come in handy. You can assume that your input is a square matrix.

2b. Check that your function agrees with Sage's built-in function on a random 5 by 5 matrix over image text in transcribed

2c. Do some timings for random image text in transcribed matrices over image text in transcribed for image text in transcribed comparing your function and Sage Math's built-in function. Make a single plot containing both sets of results.

2d. Explain the results of 2c in terms of the asymptotic complexity of the two methods.
