mathodman Posted June 17, 2019 Share Posted June 17, 2019 Let for j = 0,. . ., n aj = a0 + jd, where a0 and d are fixed real numbers. Calculate the determinant of the matrix A of size (n + 1) × (n + 1). Matrix A is below Link to comment Share on other sites More sharing options...

MotleyNoumenon Posted July 8, 2019 Share Posted July 8, 2019 Apply the definition? look at the symmetry, maybe use some known decomposition of this sort of matrix and apply properties of the determinant.. these are just thoughts.. Link to comment Share on other sites More sharing options...
Mordred Posted July 26, 2019 Share Posted July 26, 2019 As I don't simply want to give the answer. Once you have the matrix entries and type of matrix figured out. Follow the following rules to get the determinant https://www.mathsisfun.com/algebra/matrix-determinant.html Link to comment Share on other sites More sharing options...
