Coming from the girl that thinks that infinity/infinity --> 1Your 2U maths mark will not count at all if you do 4U, whether you are doing it in a high school or not
Wow, i thought you said "w/e" lol. And it's amusing how you can't take a joke XDComing from the girl that thinks that infinity/infinity --> 1
A joke? :S No you were dead serious.Wow, i thought you said "w/e" lol. And it's amusing how you can't take a joke XD
Nope.hmmm i thought infinity/infinity = 1
i also thought 0/0 = 1
I dunno if you'd call 0/0 undefined. It's more mathematically indeterminable. I think...hmm i was only kidding about the 0/0 = 1 its undefined but i didnt know about the infiinity one.
It is in the HSC to simplify things but as everyone knows, the HSC =/= real life ^_^hmmm i thought infinity/infinity = 1
xD
[serious]I said it was a joke on msn when it was clear you thought i was serious and it's not like i haven't blocked you beforeNope.
They're both mathematically indeterminable (or meaningless).
See above for the four cases of an expression being mathematically indeterminable.
The sad thing for our friend Anna is that she's already done 4U maths, doing uni maths and is tutoring students.
Once I explained to her why she was wrong (ie. why infinity/infinity =/= 1) she said I was being illogical and blocked me from MSN. Now she says that it's was a joke...
jm01 hasn't perfected the art of detecing sarcasm online, which is somewhat understandable.hmm i was only kidding about the 0/0 = 1 its undefined but i didnt know about the infiinity one.
Hmm yes. Then what value does lnx/x approach as x-->infinity? According to you it approaches 1, when it infact doesn't. Furthermore, you could get a question asking you to graph this. You would seriously mislead students in these types of questions if you told them that infinity/infinity=1 to "simplify" things.It is in the HSC to simplify things but as everyone knows, the HSC =/= real life ^_^
News flash, I actually haven't PMed you since you blocked me last timeI just find it amusing that you say you "don't care" but then you pm me or follow around me on BOS complaining about being blocked.
There you're wrong again. The two are not interchangeable.[serious]Oh and undefined = mathematicall indeterminable[/serious]
I said that it's only the case for the HSC, ie for basic questions one would get in the HSC.Hmm yes. Then what value does lnx/x approach as x-->infinity?

Similarly your "theory" fails too with x/e^x as x--> infinity.
Notice the word "or"?News flash, I actually haven't PMed you since you blocked me last time
Ok, you gave cases and defined what they are. Now define what "undefined" means and what "mathematical indeterminable" means. I was told by my teacher they are basically the same thing, but apparently i'm wrong so do spread your knowledge.There you're wrong again. The two are not interchangeable.
For example. 2/0 is undefined, whereas the 4 cases above are mathematically indeterminable. Of course one could argue that if an expression is mathematically indeterminable then it's undefined. But not the other way around.
You usually can find the limit of a mathematically indeterminable expression (one way is to use L'Hôpital's rule) whereas for something that yields an undefined answer (like 2/0), you are unlikely to find that a limit exists.
I think you should stick with infinity/infinity=1
Ohhh... so BASIC questions huh...I said that it's only the case for the HSC, ie for basic questions one would get in the HSC.
Look in the Coroneos 2U book. There's a good explanation there in the limits chapter.Ok, you gave cases and defined what they are. Now define what "undefined" means and what "mathematical indeterminable" means. I was told by my teacher they are basically the same thing, but apparently i'm wrong so do spread your knowledge.
Anything over 0 is undefined.I dunno if you'd call 0/0 undefined. It's more mathematically indeterminable. I think...
Undefined would be something like 2/0
Perhaps. But it's be more specific if you called the four cases above as being "mathematically indeterminable".Anything over 0 is undefined.
And the difference between "undefined" and "mathematically indeterminable" is?Perhaps. But it's be more specific if you called the four cases above as being "mathematically indeterminable".
Sorry, what cases?undefined is like 2/0 (which approaches infinity).
Mathematically indeterminable is described by the 4 cases above.
