Well, I havn't been to these messageboards in . . . awhile, so maybe I don't know if everybody here has seen this.
I guess I'm just posting it; comment if you'd like!
she also mentioned how the ranges and domains get reversed "so much."
Well, maybe I'll try to find something else to bother you all with that you'll like,
my current teacher mentioned in passing something about the domain of a composite function, but she said it wasn't something that gets talked about till a 500 level calculus class, so, hopefully, I won't have to worry about it right now; also, maybe that is why these calculus texts I can so far...
inverse image isn't part of the vocabulary as taught to me, so your using something I havn't even seen; maybe when I get higher, there will be a more proper demonstration; I'm thinking by inverse image, your meaning range. Also, what does wrt mean?
Anyways, I'm seeing a transitive property...
my previous calculus teacher stressed finding the domain of a composite function; he stressed more of finding which areas were not part of the function by means of three circles and saying the function didn't pass to the other circle unless it met the range of the other function. The textbook...
I only skimmed the book too many months ago . . .
. . . I'd recommend Morris Kline's "Mathematics: The End of Certainty."
Or even E.T. Bell's "The Development of Mathematics."
Still, it is exciting to find a place with over seven thousand members, and probably at least 95% of them are...
My points about Carl Sagan's "Cosmos"
It was not stricktly about science, its methods and results; it was about science and the human condition.
Somebody has to say these things, and Carl Sagan unlike plenty of other scientists had the balls to say them. :wink:
