Topics covered in Area for JEE Advanced Mathematics.
Topics in Area
1
Area Bounded by Curve and X-axis
- If f(x) ≥ 0 for x ∈ [a,b], then area = ∫ᵃᵇ f(x)dx
- If f(x) ≤ 0 for x ∈ [a,b], then area = ∫ᵃᵇ |f(x)|dx = -∫ᵃᵇ f(x)dx
- When curve crosses x-axis, split integral at intersection points
2
Area Between Two Curves
- Area = ∫ᵃᵇ |f(x) - g(x)|dx where f(x) and g(x) are two curves
- Find intersection points by solving f(x) = g(x)
- Upper curve - Lower curve gives positive area
3
Area with Multiple Intersections
- When curves intersect at multiple points, split the integral
- Identify which curve is upper in each subinterval
- Sum areas of all subregions
4
Special Cases and Techniques
- Parametric curves: Area = ∫ᵗ¹ᵗ² y(dt/dx)dt = ∫ᵗ¹ᵗ² y(t)x'(t)dt
- Polar curves: Area = (1/2)∫ᵅᵝ r²dθ
- Areas involving inverse functions
