Key Topics to Revise
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
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
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
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
