Calculus 1
- Free
- No certificate
Calculus 1 is Khan Academy's single-variable calculus course, arranged in eight units. It begins with limits and continuity, estimating limits from graphs and tables before finding them by substitution, factoring, conjugates and trig identities. Two units cover derivatives: the definition and basic rules, then the chain rule and other advanced topics. Applications of derivatives and analyzing functions follow, then integrals, differential equations and applications of integrals.
The page lists 171 skills. Each unit is a sequence of lessons with practice, quizzes at intervals and a unit test, and a course challenge covers the full course; the site tracks each skill from Not started to Mastered. As with everything on Khan Academy, the course is free with no paid tier, and there is no certificate or credit. No duration is stated, so you can move through it at your own speed or use it to shore up specific topics alongside a class.
What you’ll learn
- Estimate and compute limits and reason about continuity
- Differentiate using the basic rules, the chain rule and related techniques
- Apply derivatives to rates of change, optimization and function analysis
- Compute integrals and use them in applications such as area and accumulation
- Solve basic differential equations
Who it’s for
Students in a first calculus course or preparing for one, and anyone reviewing calculus before a quantitative degree. It assumes you are comfortable with algebra and trigonometry.
