Calculus I
Limits, Derivatives and the Fundamental Theorem
Calculus I introduces limits, the derivative and the definite integral, and connects them through the Fundamental Theorem of Calculus.
What you'll learn
Each unit lists the ideas it develops and the skills educators check for.
What mastery can look like
Students should increasingly be able to:
- Compute derivatives accurately and explain what they represent
- Set up an optimization or related-rates problem unaided
- Interpret a definite integral as accumulated quantity
- Justify results using theorems and their hypotheses
- Work through unfamiliar applied problems independently
Common learning challenges
Where understanding most often breaks down in this course:
- Precalculus algebra and trigonometry gaps
- Setup difficulty on word-based applications
- Chain rule and implicit differentiation errors
- Pace of a university semester
Prerequisite skills
These are common foundations that may support success in this course — not admission requirements.
- Algebraic manipulation
- Functions and their graphs
- Trigonometry
- Exponentials and logarithms
- Equation solving
What this course builds
Calculus I is a prerequisite gate for engineering, physical sciences, economics and many health pathways.
Signs a student may need support
- First midterm was well below expectation
- Class notes make sense but problem sets do not
- Time is running out before the drop deadline
What progress can look like
Progress looks like independent setup of applied problems, not just faster differentiation.
How we describe progressInstructional notes (for educators)
- Prerequisite dependency: trigonometric derivatives require secure unit-circle recall.
- Common misconception: the derivative treated as a formula rather than a rate.
- Teach setup separately from computation for related rates and optimization.
- Reasoning expectation: theorem hypotheses checked explicitly.
- Progression toward independence: mixed problem sets that do not name the technique.
