My lack of any shred of idea about the concept of the determinant is really beginning to bug me. Especially now that I have begun my Linear Algebra class. Is there anybody available to help explain (or link me to a good explanation) to me the idea behind it and what the value actually stands for? The whole process seems like magic to me so far. Even my book skips on really explaining anything when the determinant is introduced. This annoys me the most when using the cross product. How is it that the determinant of the matrice is the magnitude for the new vector?
