    Question Matrices `

    is there a faster way to find the determinant of a matrix that is greater than a 3 x 3, finding cofactors are so time consuming, and my teacher showed us a way but he couldn't explain it very well

    i have it in my notes but i get lost

    Not as far as I've been taught. I'd also be interested if there were an easier, quicker method.

    Have you taught in how to turn a matrix into triangular one? That helps sometimes, 'cause the determinant is just the product of the diagonal.
