I am waiting for Siouxie to give us an answer on this.

Actually, it is wrong. Whoever drew up that example did not do it correctly
and made a goose of it.
a=b
a^2 = ab
a^2 + a^2 - 2ab = a^2 + ab - 2ab
2(a^2 - ab) = a^2 - ab
The rest will fit into place.

The fallacy is in the given, a=b. "a" does not equatl "b"
any more than circles are square. In an equation where you can just make things
up, anything is possible. Even 2=l

i understand what your getting at 27229, but what if "a" is a
function and "b" is the tangent line approximation of the function
"a". Given a domain of "b" where it closely approximates
"a", mathamaticians frequently (and must) substitute values of
"b". im sorry to inform you that "a" can equal "b"

Anonomus@27229 is right. A = B or the 2nd assumption is BS.

beast - that aint no assumption - ive taken enough calc to show its true. Thats
actually pretty much the entire idea behind calculus. Using derivatives, tangent
lines, tangent planes, ect to determine values relating to a function. If you
limit the domain of a derivative, it will (for all practical purposes) be equal
the original function in that domain. you can substitute a for b because they
can be equal. Its no different than the sin of theta for small numbers is
approximately equal to the tan of theta for small numbers.

Uh .. wrong. a2=ab is an assumption. A bad one. One that shows this to be
miserably false on all counts.
Keep trying geek.

line 4, (a-b)=0, so you can't go from line 4 to line 5
because, if you have 0*anynumber = 0*anyOTHERnumber, you can't, and mustn't say
: anynumber =anyOTHERnumber but 0=0 (latĂȘtatoto!)!
Anonymous Report This Comment Date: April 05, 2006 03:13PM
hum, little problem with the formula.. this is
"0*anynumber=0*anyOTHERnumber"
And "anynumber=anyOTHERnumber"
and "0=0"

Does any of you know why in these kinds of computations one can't divide by
zero?
cesiuminjector Report This Comment Date: April 05, 2006 06:19PM
in layman the reason you cannot divide by zero: how many times can something go
into nothing
im sure this is a fallacy, but its not readily apparent to me why
in line 4, there is just the expanded a^2-b^2 which is equal to (a+b)(a-b), it
doesnt say a*b anywhere in line b. The next algebraic operation is to devide
(a-b) from both sides of the equation - which is perfectly legal
nevermind - im going to send this to one of the math proffesors at cal poly -
they will respond back with the right explanation

x=0.9999... repeating
10x=9.9999... repeating
10x-x=9
x=1
how can x=0.9999... repeating and x=1???
explain please
shaDEz Report This Comment Date: April 05, 2006 08:44PM
i'm guessing it is estimating to =1 when you forced a conclusion out of it
it is safe assume
if x=0.9999...
then 10x-x=9
even though it would actually be 8.9999...

i can supply you with more math phenomena - like how the line y= (1/x) where
x exists from 1 to positive infinity and then this function is rotated about the
x-axis (makes a giant funnel shape lying on its sided). This shape has infinite
surface area, yet finite volume.

The point with division by zero is that division is the inverse of
multiplication, when you multiply something by zero you always get zero, and you
never get a number different from zero. Th function of multiplying by zero is
nor injective neither injective, so it cannot be inverted.
In other words if n*0 = 0, and you try to divide 0 by 0 you cannot say what what
was the value of n. Moreover, no number M different from zero can be the result
of an operation n*0=M thus, given M you can't find out what was n.
