Conic Sections Part 1

IPOD VIDEO:
In this unit we study the conic sections. These are the curves obtained when a cone is cut by a plane. We find the equations of one of these curves, the parabola, by using an alternative description in terms of points whose distances from a fixed point and a fixed line are equal. We also find the equation of a tangent to a parabola using techniques from calculus, and we use this to prove the reflective property of the parabola.

Equations of a Straight Line Part 1

IPOD VIDEO:
In this unit we find the equation of a straight line, when we are given some information about the line. The information could be the value of its gradient, together with the co-ordinates of a point on the line. Alternatively, the information might be the co-ordinates of two different points on the line. There are several different ways of expressing the final equation, and some are more general than others.

There are several different ways of expressing the final equation, and some

Polar co-ordinates

The (x, y) co-ordinates of a point in the plane are called its Cartesian
co-ordinates. But there is another way to specify the position of a point, and
that is to use polar co-ordinates (r, theta). In this unit we explain how to
convert from Cartesian co-ordinates to polar co-ordinates, and back again.

Properties of straight line segments

In this unit we use a system of co-ordinates to find various properties
of the straight line between two points. We find the distance between the two
points and the mid-point of the line joining the two points.

The geometry of a circle

In this unit we find the equation of a circle, when we are told its centre and
its radius. There are two different forms of the equation, and you should be

The gradient of a straight line segment

In this unit we find the gradient of a straight line segment, and the

lines.
