I know what a determinant is and how to solve for it, but in the case of this n x n matrix on my homework, I'm at a complete loss as to how to even begin starting this. I don't expect anyone to work it out for me, just to give me a solid method for how to solve it and prove my method for the n by n case.(adsbygoogle = window.adsbygoogle || []).push({});

The problem states to find the determinant and prove our result for the n by n case for the square n by n matrix defined as:

This is the square (n x n) tridiagonal matrix with 'b' on the first and third diagonal and 'a' on the primary diagonal. Thanks everyone for your help in advance :)
