Key Topics to Revise
1
Cartesian Coordinate System and Basic Concepts
- The Cartesian coordinate system uses two perpendicular axes (X-axis and Y-axis) intersecting at the origin O
- Any point in the plane can be represented by coordinates (x, y) where x is the abscissa and y is the ordinate
- The coordinate plane is divided into four quadrants with different sign combinations
2
Section Formula and Point Division
- Section formula helps find coordinates of a point dividing a line segment in a given ratio
- Internal division occurs when the point lies between the two given points
- External division occurs when the point lies outside the line segment
3
Equations, Functions, and Their Relationships
- An equation has the form f(x) = 0, representing equality between left and right sides
- A function has the form y = f(x), showing relationship between variables x and y
- Every function y = f(x) can be converted to equation f(x) = 0 by setting y = 0
4
Graphical Representation and Function Types
- Linear functions appear as straight lines on the coordinate plane
- Quadratic functions appear as parabolas (U-shaped or inverted U-shaped curves)
- Cubic functions have characteristic S-shaped curves with possible local maxima and minima
