1. ## General Questions about the TOK course/requirements/criteria

A tok essay without counter claims is like a sandwich without bread... it just doesn't work. OK, so I bring up a point, and then give a counter-claim, but then must I say which claim I believe is better or should I just bring them both up?
2. ## General Questions about the TOK course/requirements/criteria

I'm starting up my TOK essay, and was wondering if it's like the presentation in the regard that you should always include counter-claims. Should it be like make a point, show it in a real-life example, counter-claim, and then move on, or do you have to give a final opinion about whether you agree with the original claim o the counter-claim, or is the counter-claim even necessary?
3. ## Nov11/May12 #3 Examine the claim that it is possible to attain knowledge despite problems of bias and selection using history and at least one other AoK

It says to "attain knowledge" in the title. Does that mean 100% accurate knowledge, or just knowledge to a certain degree of accuracy. Or is that open to interpretation, and I should make it clear how I interpreted that in my introduction.
4. ## IA Type II -- Population Trends in China

OK, so on top of my last question regarding how should I justify my choice of graph, it asks to "revise your model if necessary". My model fits really well, with the exception of the final two points. Should I just be like "close enough" (in fancy terms, of course) and is the function I am supposed to be getting (This is before the researcher's function is introduced) a sixth polynomial function? If it's not, then my function is just incorrect. Also, what does "Discuss the implications of each of these models..." mean? Models are just the researcher's model and the model you derived, correct?
5. ## IA Type II -- Population Trends in China

Unfortunately, I am confused... It says "What type of functions could model the behaviour of the graph?" I got sixth polynomial because I tried every trendline in Excel, and this one was the best, but somehow I feel that is not an appropriate explanation for IB... How would I explain my choice, as it asks for. Also, it says "choices" in the portfolio. Am I supposed to pick more than one trendline, or something? I really think it's sixth polynomial, though, since it gave me a superb trendline.... I kind of wanted to justify my choices through a mix of just looking at the graph, but also comment
6. ## IA Type I -- Infinite Summation

You're talking about the first side of the math portfolio, correct? In that case, when you look at the graphs you should see all the graphs have the same shape. Look at what consistently happens for each graph; it suggests something about n as Sn approaches infinity. Use that to get the first formula.
7. ## IA Type I -- Infinite Summation

Oh haha ok. Btw I thought it was the stellar numbers IA haha that's why I was like how the heck could you use excel for this?? lol I think Ms. Excel works best for this infinite summation IA. How to Use Ms. Excel 2007 for Infinite Summation IA Open your Ms. Excel 2007 In cell B2, put a In cell C2, put x In cell D2, put n In cell E2, put Tn In cell F2, put Sn Merge cells B3 to B13 (Select these cells, On the Home tab, in the Alignment group, click Merge and Center) Put the desired value of a in cell B3 Merge cells C3 to C13 Put the desired value of x in cell C3 Put 0 to 10 in cells D3 to D13 (
8. ## IA Type I -- Infinite Summation

Nope, the Taylor Series was never done...but we're not finished the course yet so maybe we'll do it later. Ya, I guess I'll ask my teacher.
9. ## IA Type I -- Infinite Summation

OK, so I can just use the Taylor Series to calculate the first general statement... Can I just use the Taylor Series for the second one they ask on the second page? They ask for two; one for when x=1 and the other for when x can be anything. I see how I can use the Taylor Series to find the general statement when x=1, but I'm not so sure how to use it for the other one. Also, we were never actually taught the Taylor Series in our class; is it OK for me to just say the series given in this portfolio is an example of the Taylor Series, and then provide a footnote for where I got the Taylor Serie
10. ## IA Type I -- Infinite Summation

OK, so I've read through this thread trying to figure out how to find the both general statements required in this portfolio. I know what they both are, but I did it through just examining my data... It was fairly obvious when I looked at it. I keep reading about the Taylor Series and derivatives and stuff, but we haven't done calculus yet, so it makes no sense to me (at least I think that stuff is calculus). Like, for the first general statement on the first page of the portfolio, when x has been kept at 1, I know the general statement (not 100% clear if I'm just allowed to post the general
