My research interests include Representation Theory and Combinatorics.

## Binomial coefficients mod 2...

Maple
Recently I was asked in a private email about the fastest way of calculating of binomial coefficients mod 2 in Maple. It shouldn't be a problem for anybody reading my assembly dll creation manual. Anyway, here is the assembly code,

## Mktime...

Maple
With Maple being able to access dll functions, it is easy to produce a function giving the epoch from the date and time. I give an example here for doing that with Open Watcom compiler included in Maple's distribution for Windows.

## An animation of 2 curves...

Maple
```f:=sin(t)*x*(1-x);
g:=cos(t)*x*(1-x);
plots[animate](plot,[[f,g],x=0..1],t=0..2*Pi);```

## How to color a region...

Maple
Wen-Xiu Ma recently asked in the maple-assist group,
```How to color the following region?
a:=plot([t^2,t^3-1,t=-3..3):
b:=plot([t^3+1,t^2-3,t=-3..3):
c:=plot([t^2+2,t^5-4,t=-3..3):
display([a,b,c],view=[0..5,-3.5..11]);```
