First, let me congratulate Nir Ailon of Israel for doing something
useful with the Macintosh while in 12th grade!

'NEW teeny deriver' does what it claims. Give it a function and the derivative
appears. I had some fun ploting these functions with MathPad, an interesting
plotting tool for simple tasks.

My concern is that 'NEW teeny deriver' does not use a Menu Bar nor seem
particularly friendly to switching programs. I tried it with System 7.01
and immediately had problems when I tried to switch to another program.
'NEW teeny deriver' did not create the Menu Bar again, did not release
computer to the other program. Stuck? I don't often have cause to use
'Command-option-escape' to force quit a program, glad it is there though.

'NEW teeny deriver' does appear to safely quit when its 'q' quit command
is used, just don't try to switch windows. Give it a try with caution and
send Nir a postcard and $5 if you find it useful!
