The Pre-Calculus category is for questions about mathematics prior to calculus. This includes the basics of algebra, trigonometry, functions, and graphs.
About: The Differential Calculus category includes questions about limits, derivatives, continuity, and their applications.
The Integral Calculus category includes questions about integrals, infinite sums, and their applications.
The Multivariable Calculus category includes questions about multivariable functions, partial derivatives, and multiple integrals.
Statistics topics include questions about data, probability, distributions, and inference.
The Differential Equations category includes ordinary and partial differential equations and their applications. Solutions might be symbolic or numeric.
The Foundations Category concerns writing, logic, and all theoretical aspects of mathematics.
The Linear Algebra category includes questions about matrices, vector spaces, linear mappings, and eigenvalues.
The Complex Variables category includes questions about the algebra and geometry of the complex number system.
The Abstract Algebra category includes questions about groups, rings, and fields.
The Real Analysis category includes theoretical questions about the foundations of calculus and the real number system.
The Contests category is for students who are interested in challenging mathematical problems - like the ones found on the Putnam Exam or the VA Tech Regional Competition.
The Computers and Code category is for questions about computational tools that we use in mathematics and statistics. These tools include LaTeX, Matlab, Mathematica, Wolfram|Alpha, Sage, Python, R, and Desmos.
