In this video, we explore determinants and what they reveal about linear transformations. We build a clear geometric intuition for how determinants measure the scaling of area (in 2D) or volume (in higher dimensions), and how they connect to eigenvalues. Finally, we cover simple and practical ways to compute determinants.
