The width of an image divided by its height is known as the aspect ratio of the image.
the aspect ratio of a traditional TV screen is 4:3 but some high definition movies prefer the 16:9 standard.

]]> <![CDATA[Distance / Norm]]>

This is a simple vector construction animation. Click and draw three vectors then drag them around the plane. The distance between the two end points (norm) of each vector is automatically shown.

]]> <![CDATA[Norme / Coordinates]]>
Click and drag the mouse to make a vector on the screen. Its coordinates and its norm are immediately calculated.

You can move the vector around the screen.
]]> <![CDATA[Components of a vector]]>

Click and drag to draw a vector, then drag it around. You can  illustrate  translation by observing  the coordinates.

]]> <![CDATA[Vectors]]>
A simple animation for vector geometry. Click on the screen and draw a vector that you can drag around by clicking on its line portion (not on its arrow.

You have three vectors at your disposal to illustrate different vector constructions.
]]> <![CDATA[Equation of a line]]>

Construction of a line joining two points. You can move this line around and display its equation.

The general equation of a straight line is given in the form y = mx+b where m stands for the gradient (slope).

]]> <![CDATA[Vector addition]]>

A graphic illustration of a vector sum.
You can change A and B by simply clicking and dragging.

]]> <![CDATA[Polar coordinates 2D]]>

Polar coordinates. These are the 2D projection of the 3D cylindrical coordinates.
This system is well suited for the study of systems with circular symmetry.

]]> <![CDATA[Polar coordinates of a vector]]>
Click and drag points A and B.]]> <![CDATA[Trigonometric circle]]>

The trigonometric circle. You can increase the angle step by step by clicking on [next-step].
