UMN MATH 2243: Linear Algebra and Differential Equations
MATH 2243 packs two subjects into one UMN course: linear algebra (matrices, vector spaces, eigenvalues) and ordinary differential equations (first and second order, systems). It's the standard post-calculus requirement for engineering and many science majors, and the two halves connect: eigenvalues come back to solve ODE systems.

What makes it hard
The pace is the problem: each half would normally get its own semester, so concepts arrive fast and the abstraction of vector spaces lands before the computational comfort does. Students who treat linear algebra as just matrix arithmetic get caught when exams ask conceptual questions about independence, span, and eigenvectors, and again when the ODE-systems unit assumes those ideas fluently.
What you'll cover
- • Matrix algebra and systems of equations
- • Determinants
- • Vector spaces, span, and independence
- • Eigenvalues and eigenvectors
- • First and second order ODEs
- • Systems of differential equations
The MATH 2243 study guide
How to study for UMN MATH 2243, step by step.
- 1
Respect the compressed pace from day one
MATH 2243 covers two semesters' subjects in one, so a missed week costs double. Set the weekly study rhythm immediately; this course punishes catch-up mode more than most.
- 2
Learn the concepts, not just the algorithms
Row reduction and determinant computation are easy points; exams also ask what independence, span, and eigenvectors mean. For every computation, practice stating in a sentence what the result tells you.
- 3
Make eigenvalues genuinely solid mid-course
Eigenvalues return at the end to solve ODE systems, so a shaky middle unit becomes a failed final unit. Drill the full pipeline (characteristic polynomial, eigenvalues, eigenvectors) until clean.
- 4
Build an ODE method-recognition habit
Separable, linear, homogeneous, undetermined coefficients: exams hand you an equation and the first skill is naming its type. Practice classification on mixed sets before practicing solutions.
- 5
Connect the halves before the final
The course's payoff is linear algebra solving ODE systems. Before the final, work systems problems start to finish (matrix setup, eigenvalues, general solution), because that synthesis is prime final-exam material.

FAQ
Is MATH 2243 at UMN hard?
The pace is the challenge: linear algebra and differential equations each usually get a full semester, and 2243 does both in one. Students who keep up weekly and learn concepts alongside computations manage it; anyone who falls behind faces a double catch-up.
Should I take MATH 2243 or MATH 2142/2373?
It depends on your major's plan. UMN offers several linear algebra/ODE paths, including the CSE variants. Check your degree audit; 2243 is the standard combined course for many engineering and science tracks.
How do I study for MATH 2243 exams?
Drill the computations until fast, then practice the conceptual layer: explaining what span, independence, and eigenvectors mean, and classifying ODEs by type before solving. Exams test both layers, and the conceptual questions decide the curve.
More UMN courses
MATH 1271: Calculus I
MATH 1271 is UMN's mainline Calculus I: limits, derivatives, applications of differentiation, and the start of integration. It's required across CSE and the sciences. Large lectures pair with TA-run recitations, and the grade rides on common midterms and a comprehensive final.
MATH 1272: Calculus II
MATH 1272 continues UMN's calculus sequence: integration techniques, applications of integrals, sequences and series, and parametric and polar material. Students widely call it the harder half of the sequence, with the same large-lecture, common-exam format as 1271.
MATH 2263: Multivariable Calculus
MATH 2263 extends calculus to several variables: partial derivatives, multiple integrals, vector fields, and the big theorems (Green's, Stokes', divergence). It's required across engineering and the physical sciences and is the visual-spatial member of UMN's calculus sequence.
