Im waiting online so please if there is any1 currently online who knowz how to find the determinat of a matrix that is larger than 3 please teach or if you know a site where i can find such a thing please inform moi . Im waiting!!!

 

thanx

I strongly suggest you do it by row reduction; follow all the usual rules until one row or (column) has all but one zeros. then you have a number to multiply the rest of the matrix by. if the reduced matrix is still larger than 3x3 then carry on doing that with successively smaller matrices. Sorry I am terrible at remembering terminology so I can't explain it well.
