Key Points: Symmetry
| Type of Symmetry | What to Replace | Condition | Result |
|---|---|---|---|
| About y-axis | Replace (x) by (-x) | Equation unchanged | Symmetrical about the y-axis |
| About x-axis | Replace (y) by (-y) | Equation unchanged | Symmetrical about the x-axis |
| About origin | Replace (x) by (-x), (y) by (-y) | Equation unchanged | Symmetrical about the origin |
| About y = x | Interchange (x) and (y) | Equation unchanged | Symmetrical about the line y = x |
| About y = −x | Replace (x) by (-y), (y) by (-x) | Equation unchanged | Symmetrical about the line y = −x |

Key Points: Geometrical Interpretation of Definite Integral
The area bounded by the curve y = f (x), the x-axis and the ordinates. x = a, x=b is \[\int_a^bydx\].
Sign of Area:
| Condition | Result |
|---|---|
| Curve above the x-axis | Area is positive |
| Curve below the x-axis | Area is negative |
| Curve cuts the x-axis | Integral ≠ actual area |

Formula: Area between Two Curves
\[\text{Area between two curves}=\int_a^b[\text{upper curve - lower curve}]dx\]
\[\text{Area between two curves}=\int_{a}^{b}y\mathrm{of}f(x)dx-\int_{a}^{b}y\mathrm{of}g(x)dx\]
