Ohio State MATH 2153: Calculus III
MATH 2153 is multivariable calculus: partial derivatives, multiple integrals, and vector calculus through Green's, Stokes', and the Divergence theorems. It follows MATH 1152 and serves math, physics, and science majors heading into upper-division coursework.

What makes it hard
The computations are often easier than Calc II, but everything happens in three dimensions, and students who can't visualize surfaces and regions struggle to set up the integrals that exams actually grade. Choosing coordinates (rectangular, cylindrical, spherical) and getting integration bounds right from a region description is where most exam points are lost, long before any integral is computed.
What you'll cover
- • Vectors, dot and cross products
- • Partial derivatives and the gradient
- • Optimization and Lagrange multipliers
- • Double and triple integrals
- • Cylindrical and spherical coordinates
- • Line and surface integrals
- • Green's, Stokes', and Divergence theorems
The MATH 2153 study guide
How to study for Ohio State MATH 2153, step by step.
- 1
Practice sketching regions from day one
Setup is the tested skill in MATH 2153, and setup starts with seeing the region. Sketch every domain and surface by hand, even badly; the visualization muscle is the course.
- 2
Drill bounds-writing as its own skill
Take region descriptions and write the integration bounds without computing anything. It isolates exactly the step where exam points die.
- 3
Learn the coordinate-choice heuristics
Symmetry in the region tells you the coordinate system. Make the rectangular-cylindrical-spherical decision explicitly on every practice problem until it's fast.
- 4
Connect the big theorems to pictures
Green's, Stokes', and Divergence make sense as statements about boundaries and interiors. Draw the picture for every application; exams test whether you know which theorem applies and why.

FAQ
Is MATH 2153 easier than MATH 1152?
Many students say yes. There's no series unit, and the integrals themselves are routine. But the 3D setup work is new and genuinely hard for anyone who struggles to visualize: most lost points come from wrong bounds or coordinate choices, not bad integration.
What should I review before MATH 2153?
Integration techniques from 1152 and the trig you'll need for cylindrical and spherical coordinates. You don't need series. Comfort with parametric curves helps for the vector calculus half.
How do I get better at setting up multivariable integrals?
Practice the setup in isolation: take region descriptions and write bounds without computing the integral. Sketch every region. After enough reps the translation from words to bounds becomes mechanical, and that's the majority of what exams grade.
More Ohio State courses
MATH 1151: Calculus I
MATH 1151 is Ohio State's standard first-semester calculus course, covering limits, derivatives, and an introduction to integration. It is required for most STEM, pre-med, and business-adjacent majors, which makes it one of the highest-enrollment courses on campus, taught in large lectures with recitation sections.
MATH 1148: College Algebra
MATH 1148 is Ohio State's college algebra course (functions, polynomials, rationals, exponentials, and logarithms) and the on-ramp to precalculus and the calculus sequence. Thousands of students take it every year, many placed there by the math placement test rather than by choice.
MATH 1172: Engineering Mathematics A
MATH 1172 is the accelerated second calculus course for engineering majors, combining integration techniques, sequences and series, and an introduction to multivariable ideas into one five-credit semester. It follows MATH 1151 and is a prerequisite gate for most of the College of Engineering's sophomore curriculum.
MATH 1149: Trigonometry
MATH 1149 covers trigonometric functions, identities, equations, and applications: the trig half of the precalculus preparation for MATH 1151. It's the standard route for students whose placement score clears algebra but not trig, and it runs every term at high enrollment.
