HEY does anyone have a sample for this IA to use as reference? i have absolutely no idea what they're asking for!!! what do they mean by "model the behavior"? behavior of what? and what do they mean by the word "model"??? also, my teacher keeps going on about finding regression curves and summation of data.. but i dont understand why I have to do that! does any one have any suggestions how to do this portfolio? i really need this grade. i spent an entire week doing my Type I portfolio, but i only got 14 or 15/20 for it. im so desperate right now.

OK I started Calculus 4 weeks ago and since last week, everything was going really well, I actually get what our teacher is saying (usually it is impossible to register what he is going on about because of his awesome accent) Then we started on differentiating trig functions. . . . So i don't get it. Would someone please explain to me? How is it different from normal differentiation? Thanks so much!

So I am working on my math portfolio. It asks us to use matrix methods to find quadratic and cubic functions with the given data. From what my teacher showed us in class we need to have an inverse matrix of the variables of the equation multiplied against the y-value. for example, the x value is 2, and the y value is 23, so she told us to plug in 2 into a ax^2+bx+c formula, and to make c=1. so my matrix for that variable would be [4 2 1] = [23]. however i have 9 values, a 9x3 matrix, and inverses can only be done on square matrices, can i just break it up into 3 smaller 3x3 matrices? and am i finding what the constant is with this ?

So the thing is that our school goes through Mathematics SL in one year, instead of two years. We take the Maths SL exam already the first year. Eventually, if there are some who want to continue with Maths HL, they will be able to the second year. Is taking Maths SL in just one year equivalent to the first year of Math HL? Since I'm going to take Maths HL next year, will this help me(taking the whole SL course in one year)? Thanks

Hey guys, I took Math HL 1 last year as a sophmore because i was a year ahead in math, and it was only at the end of the year that our counselor found out that your not allowed to take an HL exam in your junior year. Originally i was going to take the Math HL exam at the end of my junior year and then take an AP maths course in my senior year. But now that we found out i cant take the exam next year, my school laid out some options for me and im not really sure which one to pick. The first one was that i could just skip a year of IB math and do a year of AP math before going back to math HL in my senior year. The second was that i could take math Hl 2 next year and th…

Hey, IB mathematicians. First real post, w00t! - I was just wondering if anyone knows, is the Geometry section of Further Mathematics the same as the (removed since 2004 curriculum) 'Euclidean Geometry and Conic Sections' Mathematics (HL) option? Well, not [i]exactly[/i] the same...I mean, covers basically the same areas, like bisectors and conics.

Hey guys, I am currently taking a functions course in MYP grade 10. I have taken SL Math so I have two more semesters to go. Our teacher has told us that this course will show up on our university transcripts. Now my mark isn't exactly good in this course and I was thinking I'd do good in SL math next year. So how much value does this course have and how much will universities weigh it?

Hi there. I'm just looking for some suggestions, hopefully some people have some tips. So, my situation is that only one school in Nova Scotia offers Math HL, which unfortunately isn't mine. I am quite mathematically inclined, so me and a friend are planning to study Math SL with the class, but do the HL work, etc. together and with a tutor. I'm sure we can do it, but are there any tips on what to do to make sure we can do well?

[size=4][b]This thread is dedicated to IB students like me who love to use calculators. [/size] I came across this question without using a calculator and got stuck. btw im in pre-ib maths. 13. (a) Consider the equation 2 3sin x−11sinx+6 = 0. (i) Find the two values of sin x which satisfy this equation. (ii) Solve the equation, for 0 ≤x≤180 . [/b] So basically I did it up to.... sin x= 2/3 or sin x= 3 which answers part i. then i did part ii. and i know that immediately sin x=3 is invalid/error. so im left with sin x= 2/3 either im missing something or havent been taught it but its impossible to do that even with knowing the special angles.

Ok to start off my math teacher is horrible she has not given us anything to prepare us for the IB exam. We don't even know what is going to be on it or anything; that’s just a little background information. So recently she has given us our project information and hasn't told us anything but its something we have to do ourselves and that we need to investigate something that we can write up. Well I decided to use the average Body Mass Index, height and weight of teenagers and compare them to my high school track team. After I have decided if they have a normal, under, or over BMI then I was going to compare their athletic abilities. But I have no idea how this is to be or…

Ok, so I got my first math IA back today and my teacher gave me a 15/20 on work I know is at least an 18, possibly even a 20, since I double and triple checked everything I wrote and corrected any mistakes using a 20/20 exemplar. He took off marks at places such as like Technology and Notation and such but there was no real reason for him to do that. Normally I would accept it but this is my only type I and he gave a girl in my class who did worse a higher mark while claiming that he was lowering our grades so that the IB would boost his scores up and help everyone. While I understand his reasoning there is no guarantee that he will be marked up. Do I have the right to co…

Hi, I came across this title at the international book fair at Kolkata. Since they have goofed up the fair schedule, many stalls are absent this year. I haven't seen Australia for instance or any titles from Haese & Harris yet. I would like to know from those who have read or even heard about Douglas Quadling & Hugh Neill's Mathematics for the IB Diploma Standard Level whether this book is worth buying and especially the situation with typos. Since this book is not printed in India, it will be a very expensive investment and long or many replies are welcome, although I may have to decide rather quickly so as to be able to make a purchase. It's a bird in the bush.…

What kind of math will I be doing in this class. I have signed up for it for next year. I was just wondering because I am absolutely terrible at math, but I am caught between a rock and a hard place because I took pre calc this year, so next year I can choose between AP statistics, probability (this is a total BS class and would look lame for me to take senior year), or AP Calculus (yeah right). So im pretty much deciding between AP stats and Ib math studies

First off, I would like to say all help is appreciated. I have been working on my Math Studies SL IA, I have recently completed all the math for the project... but in all honesty... the part that I'm most confused about is the format of the assessment. How is it suppose to be broken down? Does anyone have a link to the format of the assessment or something that I could use as a reference similar to this guide for Psychology? http://cranepsych.com/Psych/Internal_Assessment.html

f(x)=(-2)^x yep, that's the thing that have been bugging me for some weeks now. maybe you guys have an answer to this. Here goes: consider f(x) is an harmless function (it's not exactly a function really, keep readin) with a domain of positive natural numbers. If you graphed it it would be something like: the distance between the dots keep increasing as you see. (-2)^1=-2 (-2)^2=+4 (-2)^3=-8 now, what would happen if the function was not defined in positive natural numbers but all the real numbers? The range would be complex. (-2)^(1/2) for example. Let's say the imaginary axis is the z-axis. As the domain is still real numbers its in one dimention the graph w…

Okay this question may seem a bit dumb, but it's quite confusing to me It says in the textbook that if P(n) = n^2, then a polynomial f(n) that has one degree more than P(n) would be an^3+bn^2+cn+d So my question is: What if the polynomial I have is n^2+n? What would one degree greater than it be? (including all the coefficients)
