Today we started of with a G+ discussion (LINK HERE) of the differences between a

1. CIRCLE

2. ELLIPSE

3. PARABOLA

4. HYPERBOLA

Where Xintong's explanation was accurate and recommended by Mr Johari.

Conic Sections

A parabola has a line of symmetry, while a Hyperbola has 2 lines of symmetry, the transverse and longitudinal (Vertical and Horizontal) |

**Equations of Circles**

Discriminant

D<0

Imaginery Roots

D>0

Real and Distinct Roots

D=0

Real and Equal Roots

**Methods to finding the centre of the circle and the Radius**

Method 1 (Completing the Square)

Method 2 (Comparing Coefficients)

**General Form of the equation of a circle**

**Assignment Questions in (Further Coordinate Geometry: Equations of Circles)**

Question 5 (Tier B)

Apparently it can intersect with each other

Question 8 (Tier C)

**Closing Note**

Homework: Use GeoGebra or any graphing application to test out assumptions
