Calculus
Limits, derivatives, integrals and series: the single-variable calculus of a first university course.
A complete first course in single-variable calculus, in the order it is taught at university: limits and continuity, the derivative and its rules, the chain rule and implicit differentiation, what derivatives are for (rates, optimisation, curve sketching, the mean value theorem), the integral and the fundamental theorem, the techniques of integration, the applications of integration, and finally sequences, series and Taylor expansions.
It is for anyone who is comfortable with algebra, functions and trigonometry. Each unit ends with a quiz that mixes computation, concepts and short proofs; the final exam covers the whole course.
