FANTASTIC NEWS!

In an earlier post about a math conference I had recently attended, I
mentioned one session I had gone to about the Mira. The presentor had
stated that the Mira can be used to construct sine and cosine waves.

A few persons asked for me to give that info, and I said I was waiting
for material to be mailed to me from the presentor. Well, finally this
week it arrived.

It is a fantastic little book on how to use the Mira to construct conic
sections, since and cosine waves, plus more traditional topics. I think
this little book would interest everyone from Pre-Alg teachers up
through Pre-Calculus (and maybe others besides)

Anyway, it would be difficult for me to explain the constructions in
this medium without access to diagrams. It is better perhaps if you
order a copy of the book yourself.

I have the author's permission to post his adress here so that you can
order it.

The booklet is called _MIRAculous Constuctions_. Cost is $10.
