# Compute Determinant for 2×2, 3×3, 4×4, 5×5 Matrix via Cofactors – Step by Step – using TiNspire’s Linear Algebra Made Easy

There is a number of ways to compute determinants of square matrices depending on their dimensions. Determinants of 2×2 and 3×3 matrices can simply be computed using their set formulas as seen below: Determinants of 4×4 and higher matrices actually take advantage of determinants found for smaller square matrices using Cofactors as illustated… (read more)
