Branched from huffman coding (excellent example).  The huffman tree was not encoded in the message. The tree was known from the original message but suppose we didn't have the original message.  We need the tree in the compressed message.

How do you include the huffman tree in the message?

Having a little trouble getting Remove to work properly in Maple 12

a := "Just try to remove a letter using Maple 12's StringTools[Remove]";
                                     a := "Just try to remove a letter using Maple 12's StringTools[Remove]"
with(StringTools);

How can we import data directly from a zip file?  Does someone know how to?

Can we plot without values to variables that we know are constant or do we always need to assign some kind of a value?  

As an example lets just go back to a first/second year classical mechanics course.  We'll just use the simple case of a falling projectile.  The object has a velocity of v0, with a gravitational force mg and resistive force kmv.  Using Newtons 2nd law of motion we can set up the equation.

Anyways as always maple easily...

The plot is fine until specifying the upper limit too high at which point the lower limit on the x axis is ignored from view. Works on Maple 12, does not in Maple 16.
