Coordinate Geometry
- Given 2 points A、B. Students should know,
- Polar coordinate of A
- Length, slope and mid-point of AB
- Find point P if P divides AB into 2 parts with a ratio of AP:PB = m:n
- Find the equation of a straight line using its slope and a point passing through the line
- For parallel lines, their slopes are equal
- For perpendicular lines, m1 x m2 = -1
- Transform line Ax + By + C = 0 into the format of y = mx + c and able to determine the slope and y-intercept
- Equation of circle
- Standard form and General form
- With a given equation, able to find its centre and radius
