Key Topics to Revise

1

Derivatives of Composite Functions (Chain Rule)

  • If y = f(u) and u = g(x), then dy/dx = (dy/du) × (du/dx)
  • Chain rule is essential for differentiating nested functions
  • Always identify the outer and inner functions clearly
2

Derivatives of Inverse Functions

  • If y = f(x) and x = f⁻¹(y), then dx/dy = 1/(dy/dx)
  • Derivative of inverse function is reciprocal of derivative of original function
  • Domain and range considerations are crucial
3

Logarithmic Differentiation

  • Take natural log of both sides, then differentiate
  • Useful for functions with products, quotients, and powers
  • Essential for functions of the form y = [f(x)]^g(x)
4

Derivatives of Implicit Functions

  • Differentiate both sides with respect to x, treating y as function of x
  • Use dy/dx notation consistently throughout
  • Collect all terms containing dy/dx on one side
