UT Austin M 408K: Differential Calculus
M 408K is the first course in UT's standard-pace calculus sequence (408K, 408L, 408M), covering limits and differential calculus with thorough treatment of applications. It serves students who want the full calculus foundation without the compression of the 408C track.

Build my M 408K study planWhat makes it hard
Slower-paced doesn't mean easy — the exams demand the same problem-solving depth, and the curve still reflects UT's strong intake. The classic struggle is algebra and trig under exam time pressure: related rates and optimization problems are 80% setup and manipulation, and that's where points are lost.
What you'll cover
- • Limits and continuity
- • The derivative and differentiation rules
- • Implicit differentiation and related rates
- • Optimization
- • Curve sketching and applications
- • Introduction to antiderivatives
The M 408K study guide
How to study for UT Austin M 408K, step by step.
- 1
Use the gentler pace to fix fundamentals
M 408K exists to give the foundation real runway — spend it patching the algebra and trig that decide exam grades. Slower-paced doesn't mean optional practice.
- 2
Drill word-problem setups daily
Related rates and optimization are 80% setup and manipulation. Translating sentences into equations is a daily skill, not an exam-week one.
- 3
Attend discussion section with specific questions
It's the cheapest place to fix confusion the week it appears, and the curve still reflects UT's intake — every cleared confusion is points.
- 4
Review errors by type
Most lost points are manipulation errors, not calculus errors. An honest error log tells you whether to drill algebra or concepts.

FAQ
Is M 408K easier than M 408C?
The pace is gentler — 408K covers differential calculus thoroughly where 408C compresses it and adds integration — but the exams are still real UT math exams against a strong curve. It's the better-odds path, not the easy path.
Who should take M 408K at UT?
Students whose major allows the three-course sequence and whose precalc or AP background is thin. Engineering and CS degree plans often prescribe 408C/408D instead, so check your degree audit before choosing.
How do I pass M 408K?
Daily problems, honest error review, and early patching of algebra/trig gaps — most lost exam points are manipulation errors, not calculus errors. Discussion sections are the cheapest place to fix confusion; use them weekly.

M 408C — Differential and Integral Calculus
M 408C is UT Austin's accelerated first calculus course, covering differential calculus and a substantial dose of integral calculus in a single semester. It's the standard track for engineering, CS, and natural sciences majors, and it moves faster than the equivalent course at almost any other public university.
M 408D — Sequences, Series, and Multivariable Calculus
M 408D completes UT's accelerated calculus sequence, covering sequences and series, Taylor series, and a substantial introduction to multivariable calculus — vectors, partial derivatives, and multiple integrals. It's the second-semester course for the engineering and science track that began with 408C.
M 408L — Integral Calculus
M 408L is the second course in UT's standard-pace calculus sequence, covering the definite integral, integration techniques, applications, and the introduction to sequences and series. It follows M 408K and precedes M 408M for students on the three-semester track.
M 408M — Multivariable Calculus
M 408M completes UT's standard-pace calculus sequence with multivariable calculus — vectors, vector functions, partial derivatives, optimization, and multiple integrals. It's the third course for students who came through 408K and 408L.
