Key Topics to Revise
1
Standard Curves and Their Shapes
- Parabolas: y² = 4ax (opens right), y² = -4ax (opens left), x² = 4by (opens up), x² = -4by (opens down)
- Ellipse: x²/a² + y²/b² = 1 where a and b are semi-major and semi-minor axes
- Understanding curve orientation is essential for setting up integration limits correctly
2
Area Under Single Curves
- Area between curve y = f(x), x-axis, and vertical lines x = a, x = b is ∫[a to b] f(x) dx
- For curves below x-axis, take absolute value of the integral
- When curve crosses x-axis, split the region and calculate separately
3
Area Between Two Curves
- Area between y = f(x) and y = g(x) is ∫[a to b] |f(x) - g(x)| dx
- Find intersection points to determine integration limits
- Upper curve minus lower curve gives positive area
4
Special Cases and Standard Results
- Area of circle x² + y² = r² is πr²
- Area of ellipse x²/a² + y²/b² = 1 is πab
- Parabolic areas often involve fractional powers
