From the calendar
Official source · Faculty of Arts & ScienceA first course on linear algebra in R^n emphasizing the interplay between algebraic and geometric perspectives. Topics include systems of equations, Gaussian elimination, representations of lines and planes, dot products, subspaces and translated subspaces, bases and change of basis, projections, the rank and nullity of a linear transformation, the rank/nullity/row space/column space of a matrix, matrix inverses, determinants, eigenvectors and eigenvalues, and matrix diagonalization. While not emphasizing proofs, this course does maintain a careful distinction between vectors and their representation in a basis as well as between matrices and linear transformations.

This is a student-contributed aggregate, not an official University of Toronto record. It is also not a measure of how hard the course is — a course average moves with who enrols in it, not only with the material.
Per-term figures stay hidden until each term clears five contributors. 12 observations can support one honest number; they cannot support 12.
How well we know this course

Both a midterm and a final appear in what we hold, so this course has historically been assessed on both rather than on a single end-of-term paper.
Counts, not a library. Pyko does not host or distribute course files, and this page is not an offer to supply one — the archive is what lets these pages describe how a course is assessed, which matters most where no syllabus has been verified.

What this opens up
39 courses list MAT223H1 as a prerequisiteShowing 24 of the 29 that have a page here. The other 10 have no page yet. Listing a course here means it names MAT223H1 among its prerequisites — often as one of several ways to satisfy the same requirement, so this is what MAT223H1 makes available, not what it alone guarantees.
