Linear Algebra tutoring

Matrices are transformations. Once you see that, everything opens up.

Taught the Strang way — geometric intuition first, then the algebra. From row reduction through the singular value decomposition and applications in ML and physics.

Levels covered
  • Introductory (Math 54 / MATH 240)
  • Second-course (proof-based)
  • Applied for ML/data science
  • Grad-school prep
Topics we cover

The full linear algebra syllabus.

Vectors & vector spaces
V=span(v1,,vn)V = \text{span}(v_1, \ldots, v_n)
Matrix multiplication
(AB)ij=kAikBkj(AB)_{ij} = \sum_{k} A_{ik} B_{kj}
Determinants
det(AB)=det(A)det(B)\det(AB) = \det(A)\det(B)
Eigenvalues
Av=λvAv = \lambda v
Rank-nullity
dim(kerT)+dim(im T)=dimV\dim(\ker T) + \dim(\text{im } T) = \dim V
SVD
A=UΣVA = U \Sigma V^{\top}
Sample problem

Diagonalise

A=(2112)A = \begin{pmatrix} 2 & 1 \\ 1 & 2 \end{pmatrix}

Find the eigenvalues and eigenvectors of A, and write A = PDP⁻¹.

Linear Algebra tutoring — questions

Very common. We bridge from computation to proof by revisiting familiar theorems (rank-nullity, spectral) with rigor.
