Topics in Index Numbers
1
Area Under a Single Curve
- The definite integral ∫ᵇₐ f(x) dx gives the area under the curve y = f(x) from x = a to x = b
- If f(x) ≥ 0 in [a,b], then area = ∫ᵇₐ f(x) dx
- If f(x) ≤ 0 in [a,b], then area = |∫ᵇₐ f(x) dx|
2
Area Between Two Curves
- Area between curves y = f(x) and y = g(x) is |∫ᵇₐ [f(x) - g(x)] dx|
- Find intersection points by solving f(x) = g(x)
- Determine which curve is upper and which is lower in the given interval
3
Special Curves and Their Areas
- Parabolas: y² = 4ax, area with latus rectum = 32a²/3
- Circles: x² + y² = r², total area = πr²
- Ellipses: x²/a² + y²/b² = 1, total area = πab
4
Problem-Solving Strategies
- Step 1: Identify the curves and region
- Step 2: Find intersection points
- Step 3: Determine limits of integration
