| Prerequisite | Specific Skill | |--------------|----------------| | | Differentiation (product, chain, implicit) | | Calculus II | Integration (parts, trig substitution, partial fractions), improper integrals | | Calculus III (partial) | Partial derivatives, basic vector operations (for systems) | | Linear Algebra (co-requisite) | Matrix operations, determinants, eigenvalues/eigenvectors | Warning : Most failures in DE are not due to DE concepts, but due to rusty algebra, integration, or factoring complex roots. 4.
