shweetz Posted September 12, 2010 Report Share Posted September 12, 2010 i've gotten up to the 3d part and i can't seem to figure out how to get the maximum number of parts.the question is:A cuboid is a finite 3d object. investigate the maximum number of parts (P) that are obtained with n cut.-Use geometry software to investigate the maximum number of parts for n=1,2,3,4,and 5.if someone can help me with that question and tell me the max parts per n value i can easily solve the rest. thanks Reply Link to post Share on other sites More sharing options...
Guest IMBATMAN Posted October 7, 2010 Report Share Posted October 7, 2010 I think I'm ok at math but I dread the thought of talking Math HL next year, is there any possibility of going down to Math studies? (I heard it was easier) but will it look bad on my college transcripts? Am i stupud? help. Reply Link to post Share on other sites More sharing options...
Mahuta ♥ Posted October 7, 2010 Report Share Posted October 7, 2010 Well what I know is that math studies is taken by those who do not need it in uni. If you want to major in anything that requires math, then I don't think Math ST will look good. What are you taking now? and why are you thinking of moving to St? If you are currently in HL and want something easier, go to SL, not studies.If it makes it better, I have friends who are the smarta**es in my grade and still took Math st, just because they don't need it in uni.

Guest IMBATMAN Posted October 7, 2010 Report Share Posted October 7, 2010 I'm in SL right now actually Reply Link to post Share on other sites More sharing options...
Austin Glau Posted October 7, 2010 Report Share Posted October 7, 2010 Don't worry, taking Math Studies doesn't make you stupid. The reason Math Studies exists is for people who don't neccesarily plan on an expertise in math, and that is fine. I know lots of people who take math studies, and they are still very smart.

Mahuta ♥ Posted October 7, 2010 Report Share Posted October 7, 2010 I dread the thought of talking Math HL next yearWhy do you have to take Math HL next year?! I don't get it..Are you currently finding SL hard? Reply Link to post Share on other sites More sharing options...
Summer Glau Posted October 7, 2010 Report Share Posted October 7, 2010 Yeah don't worry about it making you look stupid...it doesn't! Take the subjects you need for uni/are interested in, and if math isn't one of them, then taking studies should be fine What would be a bad decision though is to take HL math if you don't need to/don't like math.

elmar Posted October 7, 2010 Report Share Posted October 7, 2010 I'm pretty sure if you're in IB, you won't be considered stupid. Period. Regardless of whether you take SL or Studies, Bio or Chem (or Physics), or even Environmental Science or another language as your sixth. IB is hard and, yes, some people take the easy route, but choose what you feel is best for you and your future. If you feel taking Studies would allow you to get higher scores in all of your other courses, then go for it! But if you're going to use the spare time to do something not beneficial, then that would be considered stupid. Reply Link to post Share on other sites More sharing options...

I don't get it..Are you currently finding SL hard?I'm in 11th grade taking Math SL right now, and i'm good at it. next year is HL and i have heard that it drives people towards suicide (jk Reply Link to post Share on other sites More sharing options...

It's not like two one year courses... there are three categories (basically):- Math HL- Math Sl- Math StudiesAnd you take any of these for two years, normally.

Julieee Posted October 10, 2010 Report Share Posted October 10, 2010 No, not stupid at all. I have friends in Math ST who are extremely smart. I regret not taking Math Studies so much!! I absolutely hate math and calculus. Reply Link to post Share on other sites More sharing options...
Biluz Posted October 12, 2010 Report Share Posted October 12, 2010 did anyone find the answers for this question?and also, was anyone able to prove the conjecture? Reply Link to post Share on other sites More sharing options...
prastha Posted October 13, 2010 Report Share Posted October 13, 2010 (edited) did anyone find the answers for this question?and also, was anyone able to prove the conjecture?Please let me be clear in which part you are having problem.The main clue for this HOW MANY PIECES PROBLEM is: enlist all the maximun no. of possible pieces for line, circle, cuboid and 4 d objectThe after listing them all you will notice the pattern that for any number the recursive meaning that any number is the sum of the no. directly above it and the no. left to the no. i.e. above. Sorry 4 some sort of technical mistake that imade previously @ Gene-PeerActually, its somewhat like shpownbelowDimensions(towards right) Dimension 1 Dimension 2 Dimension 3 Dimension 4No.of cuts( downward) 0 1 1 1 11 2 2 2 2 2 3 4 4 4 3 4 7 8 84 5 11 15 16Here u can see that 16 is the sum of 8i.e.above it and next 8 that is left of the one that is above.U cantry it with others as well. Imsure it will work out.Fromthistable u would be able to find any recurssive formula. Best of luck with your portfolio.....

genepeer Posted October 16, 2010 Report Share Posted October 16, 2010 how is 0 (italic zero) + 1 (italic 1) = 2 (bold 2)? or is it the special case? I'm not doing this portfolio, just reading through the forum, so I might be missing something to understand the grid/table. Reply Link to post Share on other sites More sharing options...
Teddy Posted October 18, 2010 Report Share Posted October 18, 2010 (edited) Hi, I'm doing the same math IA and got stuck on the 3D part as well, i know that if there are 1 cuts, the parts would be 2, 2 cuts maximum 3, and 3 cuts i'd say maximum 8 parts, but then i got stuck on the 4th cut, as i dont know where to start.hope this helps, and can someone help me too, since i have to turn this in soon thanks Edited October 19, 2010 by 2401 Tangents no text speak please :) Reply Link to post Share on other sites More sharing options...

suggaplum Posted October 26, 2010 Report Share Posted October 26, 2010 Hey everyone,is this the other portfolio for May 2011, since I just did the patterns within systems of linear equations and my teacher recommended us to do the other type 1 portfolio for may 2011 since it would help us with our mathematical thinking however he did not give us the sheet as he is not allowed to.Would it be possible if any one of you could send a copy of the IA for me if this is the other type 1 maths portfolio for may 2011 exams. Thanks so much in advance!I can help you guys with other any subjects Reply Link to post Share on other sites More sharing options...
hello its me Posted November 7, 2010 Report Share Posted November 7, 2010 I'm doing that as well.. And I'm stuck on n=6! :/you don't have to do n = 6 ? the task says investigate maximum number of parts for n = 1,2,3,4 and 5 1 Reply Link to post Share on other sites More sharing options...
