Key Topics to Revise

1

Definition and Basic Concepts

  • Derivative of f(x) is denoted by f'(x) and represents the rate of change
  • Process of finding derivative is called differentiation
  • Geometrically, derivative at a point represents the slope of tangent to the curve at that point
2

Power Rule and Basic Derivatives

  • Newton's Power Rule: d/dx(xⁿ) = nxⁿ⁻¹
  • This rule works for all real values of n (positive, negative, fractional)
  • Derivative of x is 1, derivative of constant is 0
3

Sum and Difference Rules

  • Derivative of sum equals sum of derivatives
  • Derivative of difference equals difference of derivatives
  • These rules allow term-by-term differentiation of polynomials
4

Product Rule

  • Used when differentiating product of two functions
  • Formula: d/dx[f(x)g(x)] = f'(x)g(x) + f(x)g'(x)
  • Remember: derivative of product ≠ product of derivatives
