Hello, Ehh, i left this homework till the last day thinking it`s not too hard, but actualy i have no clue how to completely solve any of them - Determinant: If anyone could solve just one of them it would be much appreciated! Thanks, in advance.

For the first one, try to turn that matrix into a left triangular one, then you'll get easily the determinant. As for the second question, it's just Euler's formula application.

Thanks, in advance. We know by Euler's Formula that . So Do similarly for the second.
