UW MATH 124, Calculus with Analytic Geometry I, is the first quarter of calculus at the University of Washington. It is a 5-credit course offered every quarter, including summer, and it focuses on differential calculus. This guide maps every MATH 124 topic to practice with instant feedback, so you can learn by solving problems.
What UW MATH 124 covers
The UW course catalog describes MATH 124 as the first quarter of calculus of functions of a single variable. It emphasizes differential calculus, and it emphasizes applications and problem solving using the tools of calculus. There is no formal prerequisite, but the catalog recommends completing the math department's Guided Self-Placement.
The catalog does not list subtopics. A course on differential calculus covers the first half of a standard Calculus 1 course: limits and continuity, the derivative, differentiation rules and applications such as optimization and related rates. Integration is the focus of the next quarter, MATH 125.

Example problems at the MATH 124 level
1. A derivative from the definition. For f(x) = x^2,
2. Implicit differentiation. For the circle x^2 + y^2 = 25, differentiate both sides: 2x + 2y\,y' = 0, so y' = -\frac{x}{y}. At (3, 4) the slope is -\frac{3}{4}.
3. Related rates. A 10 ft ladder slides down a wall with its base moving out at 1 ft/s. When the base is 6 ft out, the top is 8 ft up. From x^2 + y^2 = 100, 2x x' + 2y y' = 0, so
How to do well in UW MATH 124
- Keep pace with the quarter. Ten weeks goes fast. Practice a little every day with mixed derivative practice.
- Focus on applications. The catalog stresses problem solving, so spend time on related rates and optimization setups, not just rules.
- Fix algebra slips early. See common calculus mistakes for the ones that cost the most points.
- Use the formula sheet while learning, then take timed practice exams before midterms and the final.
- Plan your study with how to study calculus.
Tip: in related rates, plug in numbers only after you differentiate. Substituting too early turns changing quantities into constants.
