This time Suman Sir told us that we have to create a model for our project. The topic can be anything chosen from the following. Listening to his words, I figured that to him a model is not a mathematical model. It is a kind of 3d object.

This is what we have in our syllabus. But, you might recommend something out of this if you think it is good

Arithmetic Progressions
Coordinate Geometry
Probability
Constructions

Applications of Trigonometry
Surface Areas and Volumes
Circles
Area Related to Circles

Real Numbers
Polynomials
Pair of Linear Equations in two variables
Triangles
Trigonometry
Statistics

Wait, does he mean a 3d model or a mathematical model?

The limit operator is just an excuse for doing something you know you can't.

Thanks a lot.

The conic section and the quincunx seem interesting.

Is it possible to make a interactive unit circle without a computer?

If you had a hand cranked wheel, with a gear to drive some tractor feed printer paper you might be able to get a sine curve trace.  You need the wheel and the paper to be driven by the same method so that they stay in sync.

The lissajous pendulum does work; my A level physics teacher had one using sand; but it's hard to keep it swinging so it doesn't produce fantastic traces.  An oscilloscope or computer program is reliable but then you are not making an actual model.

The programmed quincunx is based on an actual model using a board and nails.  You'll need to experiment with the right spacing and ball size to get it working nicely. And it will only show 50:50 probabilities.

You could make a cone out of clay or plaster (or even wood) and cut sections.

Hope it goes well whatever you decide to make.

I think I will go for the quincunx. Let me talk to my team tomorrow....

Thanks again, that really helped

To be honest, my maths teacher said this is too hi-fi as for the theory. So, Nky and his team made it and he really made an awesome one

I am not getting the picture of it.

In mathematics, you don't understand things. You just get used to them.
Some cause happiness wherever they go; others, whenever they go.
If you can not overcome with talent...overcome with effort.
