Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Given matrices A = [1, 2; 3, 4] and B = [5, 6; 7, 8], determine if they are invertible, and if so, calculate A_inv and B_inv.

💡 Hint: Check det(A) and det(B) for non-zero values.

Challenge 2 Hard

Solve the linear equations A x = b for A = [2, 3; 4, 5] and b = [8; 18].

💡 Hint: Use SCILAB's linsolve function to find x.
