12 A level Mathematics Calculus Differentiation from First Principles Part1 Video 3

In this video, Kristina introduces the fundamental concept of differentiation from first principles, a crucial topic in A-level mathematics calculus. She explains the definition of the derivative as a limit and visually demonstrates its meaning using a curve and two points. The video clarifies why the variable 'h' in the derivative's formula must tend towards zero without ever equalling zero. This foundational understanding is essential for calculating the gradient of a curve at any given point. Subscribe to @AxiomTutoringCourses for more A-level mathematics tutorials.
