Cornell MATH 2940: Linear Algebra for Engineers
MATH 2940 is Cornell's linear algebra course for engineers, covering systems of linear equations, matrices, vector spaces, eigenvalues and eigenvectors, orthogonality, and applications including differential equations. It's a required engineering course usually taken alongside or after the calculus sequence.

What makes it hard
Linear algebra is a conceptual subject wearing a computational costume: students can row-reduce a matrix fluently and still not grasp vector spaces, basis, rank, or what eigenvalues mean. The prelims test the abstract understanding (span, independence, the meaning of a transformation) that the mechanical homework lets you skip, so concept-skippers get surprised.
What you'll cover
- • Systems of linear equations and matrices
- • Vector spaces and subspaces
- • Linear independence, basis, and rank
- • Linear transformations
- • Eigenvalues and eigenvectors
- • Orthogonality and least squares
The MATH 2940 study guide
How to study for Cornell MATH 2940, step by step.
- 1
Chase the concepts, not just the computations
MATH 2940's trap is fluent row-reduction masking shaky understanding of vector spaces, basis, and rank. After every computation, ask what it means geometrically, because the prelims test the meaning, not the arithmetic.
- 2
Build geometric intuition for each idea
Span, independence, transformations, and eigenvectors all have visual meaning. Picture what they do to vectors and space, since the conceptual questions reward intuition that pure computation never builds.
- 3
Connect the vocabulary into one web
Rank, null space, independence, invertibility, and dimension are different views of the same structure. Map how they relate, because prelim questions probe the connections, not isolated definitions.
- 4
Master eigenvalues conceptually and computationally
Eigenvalues and eigenvectors anchor the back half and recur in applications. Practice both finding them and explaining what they represent, since exams test understanding alongside calculation.
- 5
Practice proof-style and conceptual questions
Beyond computation, prelims ask you to justify and reason. Work the true/false and short-justification problems explicitly, since they're where concept-skippers lose points.

FAQ
Is MATH 2940 at Cornell hard?
It's deceptive: the computations are mechanical, but the prelims test conceptual understanding (vector spaces, basis, rank, eigenvalues) that the homework lets you skip. Students who chase the meaning behind each computation do well; those who only row-reduce get surprised.
How do I study for MATH 2940?
After every computation, ask what it means geometrically, and connect the vocabulary (rank, null space, independence, dimension) into one web rather than isolated facts. Practice the true/false and short-justification questions, since that's where conceptual understanding is graded.
When should I take MATH 2940?
Usually alongside or right after the calculus sequence, per your engineering plan. It assumes comfort with calculus and the maturity to handle abstraction, and it feeds directly into later engineering courses that rely on linear algebra, so check your degree audit for timing.

MATH 1110: Calculus I
MATH 1110 is Cornell's standard Calculus I, covering limits, derivatives, applications of differentiation, and an introduction to integration. It's taken by students across the sciences, economics, and pre-health tracks, and it's the entry to the calculus sequence for those not on the engineering math track.
MATH 1120: Calculus II
MATH 1120 continues Cornell's standard calculus sequence with integration techniques, applications of integrals, sequences and series, and an introduction to parametric and polar topics. It follows MATH 1110 for science, economics, and pre-health students.
MATH 1910: Calculus for Engineers
MATH 1910 is Cornell's first engineering calculus course, covering single-variable differentiation and integration with an emphasis on applications, plus an introduction to infinite series and differential equations. It's a required gateway for the College of Engineering, faster-paced than the standard MATH 1110/1120 track.
MATH 1920: Multivariable Calculus for Engineers
MATH 1920 is Cornell's multivariable calculus course for engineers, covering vectors and geometry of space, partial derivatives, multiple integrals, and vector calculus including line and surface integrals and the theorems of Green, Stokes, and the divergence theorem. It follows MATH 1910 in the engineering sequence.
