The same idea can ask more of you
in the next course.
A matrix can be a calculation in MATH 347 and the beginning of a proof in MATH 577. A derivative you compute in MATH 233 becomes a linear transformation you must understand in MATH 522. The subject changes depth, and your study method needs to grow with it.
UNC Chapel Hill students already use the Woody Calculus Mastery Lab for MATH 232, MATH 233, MATH 347, MATH 383, and advanced coursework. Bring the homework, quiz topics, or exam review you are working through now.
In calculus, practice choosing the technique. In differential equations, identify the equation and its conditions. In algebra and analysis, start with the objects, assumptions, and precise claim you need to prove.
Learn the decision behind the step. Then use complete examples and deliberate practice to build an approach you can carry into a fresh problem.
Match the practice to the task
- MATH 232: explain why this integration method or series test fits.
- MATH 347 / MATH 577: connect the matrix to the transformation and the required level of reasoning.
- MATH 383: identify the equation type before choosing a solution method.
- MATH 381 and beyond: turn definitions and hypotheses into a complete argument.
Use your current syllabus to match the depth, notation, and assigned topics. The study plan follows your actual course.
From Calculus II to advanced mathematics.
Build the reasoning your course requires.
Start with your subject, then open the details for UNC’s course names, study priorities, and connections to the next level.
Calculus II
Organize integration techniques and series tests into a usable system. Learn to explain your first move before committing to a calculation.
With Woody: Choose the technique, build a clean setup, and check the result.
Course details and topics
MATH 232: Calculus of Functions of One Variable II combines integration methods and applications with sequences, series, and approximation. The course also introduces elementary differential equations.
Practice recognizing when substitution, integration by parts, trigonometric substitution, or partial fractions fits. For volumes by disks, washers, and cylindrical shells, sketch the region and axis before choosing the integral.
For an infinite series, separate the question of convergence from the question of its sum or approximation. Check the conditions of the test and the endpoints of a power-series interval. Use the Taylor series visual lesson to connect polynomial approximations with the function they represent.
- Integration techniques and method selection
- Numerical integration and improper integrals
- Areas and volumes by disks, washers, and cylindrical shells
- Sequences, convergence tests, and infinite series
- Power series, Taylor approximations, and error checks
- Elementary differential equations and course-specific applications

Move confidently between a picture, a set of coordinates, and the calculus. Give the bounds and derivatives a geometric meaning.
With Woody: Connect the region, variables, and calculation instead of guessing a setup.
Course details and topics
MATH 233: Calculus of Functions of Several Variables develops vector algebra, spatial geometry, partial derivatives, and multiple integrals.
Start a multiple-integral problem by describing the region in words and inequalities. Compare coordinate systems before calculating. For a gradient or directional derivative, identify the direction and what is changing.
Woody also supports optimization, vector fields, and line or surface integrals when they appear in your assigned work. Use your current MATH 233 syllabus to prioritize the topics and theorems your section covers.
- Vectors, planes, surfaces, and three-dimensional geometry
- Functions of several variables and partial derivatives
- Gradients and directional derivatives
- Multiple integrals and changes of coordinates
- Optimization and vector-calculus topics as assigned
- Interpreting bounds, orientation, and the final answer

Differential Equations & Mathematical Methods
Classify the equation, identify the conditions, and choose a method you can justify. Follow that structure from introductory ODEs into applied mathematics.
With Woody: Organize the solution and explain how it satisfies the original problem.
Course details and topics
MATH 383: First Course in Differential Equations studies first- and higher-order equations, applications, and systems. Linear algebra enters as needed, making matrix and eigenvalue skills useful companions to calculus.
MATH 524: Elementary Differential Equations follows MATH 383 and develops further work with linear equations, series solutions, transforms, and numerical approaches.
MATH 528: Mathematical Methods for the Physical Sciences I connects transform methods, Fourier analysis, and Sturm–Liouville problems. MATH 529: Mathematical Methods for the Physical Sciences II moves into boundary-value problems, classical PDEs, special functions, and complex-variable methods.
For a boundary problem, identify the domain and conditions before choosing a representation. For an ODE, substitute the result back into the equation and check the initial values.
- First-order equations and initial-value problems
- Higher-order linear equations and systems
- Power-series solutions and Laplace transforms
- Fourier series, Fourier transforms, and eigenvalue problems
- Heat, wave, and Laplace equations with boundary conditions
- Special functions, numerical methods, and interpretation

Linear Algebra
Understand what the matrix calculation is telling you. Connect computation to the spaces, transformations, and geometry behind it.
With Woody: Use structure to organize both the calculation and the proof.
Course details and topics
MATH 347: Linear Algebra for Applications emphasizes matrix methods and applications, including solving systems, determinants, orthogonalization, and eigenvalues.
MATH 577: Linear Algebra takes a more abstract approach. Work with vector spaces and maps develops into decomposition, canonical forms, inner products, and spectral reasoning.
These courses need different levels of explanation. Bring the exact assignment so Woody can help with the row reduction, the conceptual interpretation, or the proof. Linear algebra is a core part of the teaching portfolio, including its connections to differential equations, algebra, physics, and data science.
- Matrices, systems, and Gaussian elimination
- Span, independence, bases, dimension, and transformations
- Eigenvalues, eigenvectors, and diagonalization
- Orthogonality and Gram–Schmidt
- Decomposition, Jordan form, and spectral arguments in MATH 577
- Clear proofs and interpretation of computational results

Abstract Algebra
Work deliberately with definitions, examples, and maps. Learn why a construction is valid before applying the theorem built on it.
With Woody: Turn a promising idea into a complete proof with every assumption in view.
Course details and topics
MATH 534: Elements of Modern Algebra studies algebraic operations and structures through groups, quotient ideas, rings, and polynomials.
MATH 578: Algebraic Structures connects algebra with permutations, matrices, symmetries, linear maps, and concrete fields. Bring your course number so the study plan follows its particular emphasis.
Before using an isomorphism theorem, define the map and verify its properties. Before forming a quotient, check the required normal-subgroup or ideal condition. Use concrete examples to understand the definition, then explain why the proof works beyond those examples.
- Groups, subgroups, cosets, and quotient structures
- Permutation, matrix, and symmetry examples
- Homomorphisms, kernels, and isomorphism arguments
- Rings, ideals, and polynomials
- Field examples and connections to linear algebra
- Proof construction, examples, and counterexamples

Real Analysis & Advanced Calculus
Make the definitions do useful work. Understand how the quantifiers, estimates, and theorem hypotheses produce the conclusion.
With Woody: State the goal precisely and build the argument that reaches it.
Course details and topics
MATH 521: Advanced Calculus I treats one-variable calculus rigorously, including the real-number system, continuity, differentiation, series, and integration.
MATH 522: Advanced Calculus II extends the analysis to several variables. The derivative becomes a linear transformation, and inverse and implicit function results become important tools alongside multiple integration.
These courses build on the reasoning developed in MATH 381. Practice identifying what must be chosen, what it may depend on, and which estimate or theorem finishes the proof. Counterexamples help explain why the hypotheses matter.
- Real numbers, completeness, and limits
- Continuity, differentiability, and epsilon arguments
- Series and rigorous integration
- Derivatives as linear maps in several variables
- Inverse and implicit function theorems
- Precise estimates, quantifier order, and counterexamples

Galois Theory & Advanced Algebra
Understand the field extension and the maps that preserve it. Connect polynomial equations with the symmetries of their roots.
With Woody: Keep the base field, extension degree, and automorphism group clear.
Course details and topics
MATH 676: Modules, Linear Algebra, and Groups develops the structural algebra background for the next course. MATH 677: Groups, Representations, and Fields explicitly includes Galois theory in UNC’s graduate course listings.
Woody supports the field-theory and Galois work you bring from this sequence or an independent study. Build from irreducible polynomials and extension degrees to splitting fields, automorphisms, fixed fields, and the Galois correspondence.
Share the precise problem and the results you are allowed to use. That keeps the explanation at the right level and helps you see which structural fact makes the next step possible.
- Algebraic structure and the transition to field theory
- Irreducibility, minimal polynomials, and extension degree
- Splitting fields, normality, and separability
- Automorphisms, Galois groups, and fixed fields
- The Galois correspondence and its hypotheses
- Complete arguments matched to your advanced coursework
Number Theory
Use divisibility and congruences to find the right approach. Explain why the argument works for every required case.
With Woody: Check the arithmetic assumptions before choosing a theorem or taking an inverse.
Course details and topics
MATH 533: Elementary Theory of Numbers connects arithmetic, congruences, and proof writing, with topics extending into residue classes, number-theoretic functions, continued fractions, and Gaussian integers.
Practice moving between a divisibility statement and a modular equation. Check coprimality before using an inverse, and explain the conditions under which a system of congruences can be solved.
The habits developed in MATH 381 remain useful here: precise statements, induction, contradiction, and complete cases. Woody helps you turn numerical exploration into a readable mathematical argument.
- Divisibility, primes, and the Euclidean algorithm
- Modular arithmetic and the Chinese remainder theorem
- Euler’s function, primitive roots, and residues
- Quadratic-residue arguments
- Continued fractions and Gaussian integers as assigned
- Induction, contradiction, and complete arithmetic proofs
