- Coordinates.
- Straight line.
- Circle.
- Conics.
- Vector.

There are 3 types of coordinates:

- Rectangular coordinates.
- Polar coordinates.
- Kertatio coordinates.

Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:

1.Inner divide.

Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:

2.Outer divide.Suppose 2 points are P(x1,y1) and Q(x2,y2) then rule is:

Find out area of a triangle:

**Circle.**

By expanding it we found:

It's center is(-g,-f) and radius,

**Conics.**

Equation of parabola:

Equation of ellipse:

Equation of hyperbola:

**At first you can print it and then hang it infront of your table.**

**After that you can get help form it.**
