Questions tagged [calculus]

Anything related to (differential and integral) calculus, i.e. the branch of mathematics concerned with the manipulations of infinitesimally small quantities. Concepts from calculus are often used in engineering to build more complex and accurate models of physical systems than those which can be built using basic algebra alone.
