i had form the matrix.
| 1 1 1..........1|
| 1 w^1 w^2 |
| 1 w^2 w^4 |
Is the matrix above correct if i leave the N-th row & N-th coloum like that?
Consider another (N × N) square matrix S such that the (c, d)-th element of S is given by Scd = w^(c-1)(d-1), c = 1,2,....,N; d = 1, 2, ...., NShow that determinant of S is equal to the complex conjugate of the determinant of R. Note all you need to show is that S and R are complex conjugate of each other. In other words, show that ω and ω−1 are complex conjugate of each other.
Is this correct?
w^N = exp (2*pi*j) = cos 2pi + j sin2pi = 1
w^N = exp (2*pi*j) = cos 2pi - j sin2pi = -1
Let T = SR. Write the elements of T.
May i know wat is w^-2?
| 3 1+w^-1+w^-2 ........
Once again many thank you for the help
