Chuck Norris can trisect any angle and square the circle.
Chuch Norris can accurately represent pi in an algebraic series containing only five terms.
Chuck Norris is a perpetual motion machine.

I think you are making a big deal out of nothing. Navigation was accomplished by slide rule for years. Radar and the beacon locate a plane to within a few feet. Navigation aids keep a airplane on course within a few feet. Gyro compass will keep an airplane on course. Flight computers are constantly updating and maintaining course and of course the pilot would not be worried because his flying skills are not concerned by a divide by zero error. I think you are making a big deal out of nothing.

Thanks, you're right. Sorry, that "/" should not have been there. I attempted a copy and edited a mess, replacing a backslash with a slash. I should have just typed it.
ax = exp(xln(a))
I have mathcad here. It gives the same thing with 00=1.

Extra credit: can someone from the class explain the Kronecker delta? ;-) My very favorite.... It's zero, except when it's not.

That's about the funniest I've seen in a long time.

30/0=30. If a number has no divions it remains the same number. If you have a pile of apples and you divide the pile by a number, you have that number of separate piles. If you make zero dividions you stay with the same pile.
Where am I going wrong, here?

Hi, WT! If you have
a/b = c
It necessarily follows that
a = b*c
So in your example we'd have
30 = 0*30
which is clearly false.
Check out my attempt to explain it in post #70. It's the explanation you find in most algebra books. Cheers!

So zero simply doesn't apply to the real world. Since the world is filled by the nonexistence of everything everywhere, zero must be the same as nothing nowhere. Just a placeholder tool to oil math operations.
