In this video, Solving The Puzzle of Equations, we dive deep into the essential methods for solving different types of equations in Linear Algebra. Whether you're working with vector spaces, matrix polynomials, or linear mappings, understanding how to solve for unknown scalars and variables is the key to mastering this subject.

Topics Covered in This Video

• Linear Combinations & Independence: Learn how to express a vector as a linear combination of others by solving systems of linear equations to find scalars c₁, c₂, …. We also set up the equation c₁α₁ + c₂α₂ + ⋯ = θ to test for linear dependence or independence, and check the determinant of the coefficient matrix to verify independence.

• The Characteristic Equation: Understand how to form and solve the characteristic equation det(A − λI) = 0 to find eigenvalues. We also cover shortcuts for 2×2 and 3×3 matrices using trace and determinant.

• Cayley-Hamilton Theorem: See how every square matrix satisfies its own characteristic equation. We use this theorem to solve problems like finding higher powers of matrices (e.g., A⁵⁰) or even the inverse A⁻¹ without long multiplications.

• Linear Transformations (Kernel & Image): Learn how to find the kernel by solving T(α) = θ′ and how to determine the null space. We also apply Sylvester’s Law (Rank-Nullity Theorem) to compute rank and nullity effectively.
