  1. I put mining for factor x and 2050 I think I remember having problems with the factor x, because the other listed factors were so extremely general... I think I ended up choosing Urban boundary expansion though
  2. Okay one last time. ∫f(x)dx refers to the "integration of f(x)". Now, as you correctly identified area=pi. However since area = absolute of inverse, one has to consider the value of the integration. http://www.intmath.com/applications-integration/2-area-under-curve.php I quote (from the above source) : "In this case, we have to sum the individual parts, taking the absolute value for the section where the curve is below the x-axis" and "If we don't do it like this, the "negative" area (the part below the x x-axis) will be subtracted from the "positive" part, and our total area will not be cor
  3. Thank you for your response, but that was not my question. My question was if the part a) was "-pi". I do understand that part b) was 3pi, but since area is absolute integration that does not make any difference because it would cause the "-pi" to be turned into "pi". My question was, and remains, if the answer to a) was -pi. As i said, the question asked for INTEGRATION, which is negative when below the x axis. Therefore if one were to find the area, but look for the integration, one would have to consider the negative result. Nevertheless I am not sure about the answer, hence why I am asking
  4. Since the older topic (from 2012) is still blocked, while the other Math levels are accepted, I wanted to create this topic in order to initiate the discussion of Paper 1 SL in Math (TZ2). Generally, I felt that the paper was rather simple. Was I the only who felt this way? Also: On Q7 part a) The question that asked the candidate to identify the Integration of the part of the function below the x axis. As the function was not given to us, I assume most of you used the area of a circle in order to identify this value. However, the thing that worries me, is that they did not specifically ment
  5. Although the IB warns about such occurrences, I have gotten the impression that they are exaggerating heavily in order to prevent such mistakes. If you closely read the IBO website, it says that they are aware that mistakes are going to happen, and that only in the rarest cases such formality mistakes have actual consequences. Also, since this entire scanning system was implemented rather late in the year, they are most likely expecting a LOT of mistakes. Therefore I wouldn't worry too much, after all.. It seams somewhat trivial to expect the continuation of an answer in the next booklet, give
  6. Hello, I had just answered this question in another topic. I'm not sure if you are the same asker, but here is the answer I gave: Hope it helps.
  7. There are several sites that can help you with the MLA Format. These include: - www.bibme.org (This is the one I always used) - www.easybib.com (apparently also very good). Alternatively a google search will supply you with more alternatives. However no matter which you decide to take, they wont completely do the job for you. Occasionally they will not recognize a source and hence require you to fill out the form manually, which is still good, since they ensure the correct organisation, layout and of course order (alphabetical as far as I am aware). Hope this helps, best regards.
  8. Good evening, first of all I wanted to say that I do not take history and therefore am not aware of your level (HL,SL). However, I think that P3 is only for HL and will therefore grade accordingly. Please remember that the grade boundaries for this years exam are not yet official. Therefore I will use the Grade Boundaries of May 2010, making your result able to fluctuate. The IA is out of 25. Therefore 2/25= 84%, which would give you 17.6% of the total mark. P1: 21/25= 84%--> 16.8% (+17.6%= 34.4%). P2: 32/40= 80%--> 20% (+34.4%= 54.4%) P3: 32/60= 53.3%->16% (+54.4%= 70.4%) 70.4%
  9. He got those values as 26/90 is 29% yet that paper only counts for 40% of your final grade so you must divide it by 2.5. The same goes for paper 2 Thank you for helping, but, just in case, in order to make it even clearer; I calculated the percentage that you achieved on the sections by dividing the result by the total amount, followed by a multiplication of 100 in order to receive the percentage of the section that you are awarded. Afterwards, I merely calculated how much this percentage awards you in total, e.g.: you received 29% on a section that makes up 40% of your entire grade. Therefore
  10. Generally, alternate forms of the answer are accepted by examiners (at least to some extent). But the problem is that often candidates try to communicate something with an answer, without making it crystal clear and only hinting at what they are trying to communicate. Only in few cases will this award them full marks. Additionally, in several questions, there are certain terms which are required for at least parts of the total mark. These terms are underlined in the mark scheme and may not be descriptively replaced. Additionally it would be wise to "make the examiner your friend" and to at lea
  11. WTF?? This kid is a genius...... I can see your not taking math studies AHhahhaha thnx man I appreciate the help alot.! Haha, no problem. Thank you for referring to me as a genius, however that was only relatively simple addition and percentage as well as weighting calculation, and therefore not quite the most promising indication of my intelligence . All the best.
  12. Hello, I am not taking Math Studies, however I'll do the calculation for you. (Please beware that the Grade Boundaries I use are from the May 2012 Exams, and will therefore only to some extent reliably answer your question.) The IA accounts for 20% of your final grade, while each Paper accounts accounts for 40%. -Since I dont know your actual points but only grade range, ill give you a range of possibilities. (Highest possible) IB2 P1=26/90=29%(of 40%)--> 11.6% IB2 P2=28/90=31%(of 40%)-->12.4% (+11.6%=24%) IB5 IA=14/20=70%(of 20%)-->14% (+24%=38%) Sadly Any figures below IB3 are not i
  13. I have just received the information (from my teacher of the subject i was worried about) that she has once witnessed a very significant drop in grade boundary for a 7 in a specific paper. For the sake of the 24h rule i wont give exact figures, but i'll say as much that this value was 13% below the usual. I am aware that such boundaries are usually compensated for by the boundaries of other accompanied papers, however I was merely concerned about specific papers. However, this does seem to be an anomaly, hence I take your answer as the response to my inquiry about the frequency of said anomal
  14. I have a very distinct approach to religion. My parents are both scientists and hence do not follow religion, however were both raised christian by their parents. I have given this a lot of thought and decided that I like the idea of religion because it gives people something to live for. When someone is in a bad situation and prays (if it does or does not help) the belief of having someone help them will give them hope. That said, I chose to give the entire subject the benefit of the doubt and do believe in "god" or some similar power. However I strictly decline having any arguments about the
  15. Hey, I also took English B HL this year and had a question about the general marking of the exams. The thing is that the English B HL class of my school is taught by a teacher who does not "believe in perfection" and therefore marks as strict as it could possibly get. This has gone so far that several native English speakers, which are taking part in the course (for whatever reasons), have only gotten IB6's. Although I am not a native English speaker, I tend to score higher than most of them due to my ability of controlled and formal language, as well as my creativity and analytic skills. Thi
