Mathematics 3: Understanding limits and derivatives
A major stumbling block in upper secondary maths explained – without starting with set theory.
Many students learn formulas without understanding what a derivative actually means. Start by building an intuitive understanding.
Limits in three sentences
A limit describes the value a function gets arbitrarily close to as you approach a particular point.
Derivatives: the slope at an instant
A derivative is the instantaneous rate of change – the slope as the distance between two points approaches zero.
Calculation rules come last
Once you understand the meaning, the chain rule and product rule become logical rather than mysterious.
