Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Consider the vectors v_1 = [1, 2, 1], v_2 = [2, 4, 2], and v_3 = [4, 8, 4]. Show that these vectors are linearly dependent.

💡 Hint: Try row-reduction to explore relationships.

Challenge 2 Hard

For the vectors v_1 = [1, 2, 3] and v_2 = [1, a, 3], determine the value(s) of 'a' for which they are independent.

💡 Hint: Set up your system and check the determinant.
