IGCSE Maths Differentiation: Finding Derivatives - Sample Questions

In this video, we will be working through past papers questions about finding first and second derivatives of different curves.

Answers to questions at the end of this video:
4. dy/dx = 4x^3 - 9x^2 + 2
5. dy/dx = 5x^4 - 8x^3 + 4x
d^2y/dx^2 = 20x^3 - 24x^2 + 4
6. dy/dx = -16x^3 + 6x^2 - 3
d^2y/dx^2 = -48x^2 + 12x
