I need help with 2 calc-related-questions.
- Determine the value of k such that u and v are orthogonal. u = [2, k, -1] and v = [3, -2, 7]
- Determine the value(s) of k such that (2k, 3, k+1) x (k-1, k, 1 = (1, -2, 2)
The x stands as a tip to do cross-product.
(Even though they use the same variables they're two entirely different questions)
