What is the derivative of e^(x^2 - 4)?

no worries, sorry got things mixed up, graph was 1/1-x, I had 1/x-1 in my head. So I guess the asymptote is y=2 + 1/(1-x)

Thanks mate! The halving of graph 1 really helped me out! But there's one more problem, it is much much simpler than any graph i've had a problem with today, but my method is probably wrong. Ok heres the question: Q. i) Discuss the beahviour of the curve at the neigbourhood of x=1 and for very...

what makes this graph so hard to me is that it isn't like the other questions in the question, i..e it isn't (GRAPH1)^4, GRAPH1 ^4 WOULD have been 16x^4/(x^2+1)^4 this one doesn't have a 16 in it... Also the "no further calculation bit" is killing me, how do I sketch it without using calculus???

umm could you please tell me how to actually sketch the graph say like in a exam, with reference to the two other graphs and without any further calculation, thanks

Thanks deterministic, that tip really helped out, got q4 just a curve approaching y=1 and x=1, reflected in both x and y-axis, and q5 was a bowtie, Here's another one that drove me bonkers, basically there were three parts (1). Sketch y=2x/(x^2+1) --> odd function turning points (1,1) (-1,-1)...

Awesome. About q1 and q2, is that the most quickest way to sketch the graphs?

yeah, i don't know = ( but how is d(e^x)/dy = e^x and how is d(e^-x)/dy = -e^(-x) how does the derivation process come about?

Hi, I have about 6 or so question needed help with, so please bear with me... Ok: Q1: y=e^x - e^(-x) (i) determine whether it's odd or even IT'S ODD (ii) determine it's gradient, find turning points. How do I do this? (iii) then sketch the graph I sketched the graph, but the only way I did...

you know when it says without further calculation, exactly how much calculation can you do? - with relation to y' of course. Also i noticed, at x=0, y' becomes indeterminable, because y'=0/0 which is practically meaning less.... Also regarding: Are these hints just for graphs in general or...

Hi, this is a question from Terry Lee. There's five parts, I couldn't do the last part. Here's the question: Given the curve y=(x^2)/(1-x^2) a) Determine whether the function is odd or even. IT'S EVEN b) Discuss the behaviour of the curve for large values of x. APPROACHES y=-1, y=-1 is a...

Hi guys, I have both of these textbooks but I really would like to know which one of these textbooks would be better make BIOLOGY notes from. Basically which textbook is better for the BIOLOGY HSC. Here's my opinion of the books: NSW Biology is very well structured, clearly corresponding to...

Jason are you selling your biology notes? Impressive marks by the way.

Hi, I've noticed something on BOS - whenever i send a PM to someone, it never appears in my "Sent Items", however when other ppl send me PM's or reply to my PM's it appears in my Inbox. So why am I facing this problem - is it just my noobery, or is it a problem on BOS's half? thaanks guys

haha lol... why would I bother when you kind people can answer the question with such speed? =D

Seriously BOS has a serious issue here, apparently in any category of the forum, threads which have had no posts in the past month cannot be properly viewed. The only thing you see is the title, yet you can't see any posts, even though it says there are 4 pages in the particular thread. What...

Extension 2 Mathematics Past Papers 1990-2009 by Jim Coroneos with worked solutions Do you still have this book?

HEY HEY HEY HEY HEY just wondering, do you still have to BIOLOGY DOTPOINT FOR $15? And is the REGULAR biology dotpoint textbook, right? And condition is good enough that all the text is still readable, right? Sorry sounds like a stupid question but I just have to know, thanks.

THANK YOU, SO MUCH, looks like I was only a couple of steps away =( Also could you give me advice, on what situations I would have to use the q=-1/p to find the LOCUS of a point?
