Muzzammil Imran Shittu Posted April 23, 2012 Report Share Posted April 23, 2012 (edited) Sorry, this came up before and wasn't answered but what format are we supposed to use for an Internal Assessment such as this one? I've tried looking for examples online but, so far, nothing's turned up. Is there any sample IA, or, better yet, any general format I can use for my Internal Assessment?Edit:Just checked the files section and found some. Sorry!Edit 2:Aww shucks. Just found out that I can't actually use the files section. That's a bit of a bummer. Edited April 23, 2012 by Muzzammil Imran Shittu Reply Link to post Share on other sites More sharing options...

Animesh Xerxes Sharma Posted May 10, 2012 Report Share Posted May 10, 2012 Pls buddies pls tell me I. Shadow functions tasl how to get a relation of the roots of y2 and y1 Reply Link to post Share on other sites More sharing options...
MalakBasel Posted May 25, 2012 Report Share Posted May 25, 2012 I can;t seem to write an introduction that's long enough. This is the first year for IB in our school and yeah, our teachers aren't much help. I explained polynomials and complex roots and that was only 100 words. What else can I say? Thank you Reply Link to post Share on other sites More sharing options...

MalakBasel Posted June 2, 2012 Report Share Posted June 2, 2012 When applying the formula to quartics, are the two roots real and two complex, or are all four complex? Because the equation would be applied differently. Thank you Reply Link to post Share on other sites More sharing options...
rsingh3 Posted June 16, 2012 Report Share Posted June 16, 2012 When applying the formula to quartics, are the two roots real and two complex, or are all four complex? Because the equation would be applied differently. Thank you You consider both the cases; one when two roots are real and two roots are complex, and another case when all four roots are complex. See how the similar relation between real function, shadow function, and shadow generating function turns up. Reply Link to post Share on other sites More sharing options...
lazybonezzz Posted July 3, 2012 Report Share Posted July 3, 2012 Hey can anyone please tell me what the heck does it mean by expressing y2 in terms of y1 and ym? I am so confused...coz I don't want to mess that up with the general statement...HELP!!! Reply Link to post Share on other sites More sharing options...
Shahad Posted July 3, 2012 Report Share Posted July 3, 2012 First you need to find y2, y1 and ym from the functions you consider.Make separate equations for each using the same variables like a, b or whatever.Once you have that write out y2.Find something in y2 which you can replace with something from the equation in y1 and ym.A bit hard to explain, if you do not understand what i mean, how about tell me what you got for y1, y2 and ym so we can figure something out?

IBHL Posted August 3, 2012 Report Share Posted August 3, 2012 Hello guys,I just got my IA Math HL last Monday,till now I have no idea where to begin..Can anyone help me ? Reply Link to post Share on other sites More sharing options...
Kakomani Posted August 6, 2012 Report Share Posted August 6, 2012 I started by just trying to do the math, doing what the task asked. Once I had a good understanding of what I was dealing with (which was about halfway through), I started writing.If you have a hard time understanding what to do to solve the problems, try using software like GeoGebra to illustrate the functions. It's very handy, as you can use sliders to easily change the variables. At the very least, do it when you are done, to see if you did it right.

macrofire Posted August 11, 2012 Report Share Posted August 11, 2012 I've found a truly wonderful proof for the general statement. Unfortunately, it's too big to fit in this margin. At any rate, you who needs help, try playing around with the abstract algebra. If you need to model some equations with real numbers, try using SAGE math to program this with an interact function. WIth this in mind, one can do wonders trying to find the connection between a polynomial function, its shadow and its shadow generating function. 1 Reply Link to post Share on other sites More sharing options...
bxdu Posted August 19, 2012 Report Share Posted August 19, 2012 hiii use various values 2nd bullet point for part a....can we use for eg a=1 and b=1 ? i mean can we use same values for a and b ?howe many equations shud i be looking for?

bxdu Posted August 20, 2012 Report Share Posted August 20, 2012 (edited) hey hii hey peeps how do u do part a the last bullet point? on a labelled diagram......zeroes of y1 ???thanxs a lot ^^ Edited August 20, 2012 by bxdu Reply Link to post Share on other sites More sharing options...
Sword (Hubert Pomorski) Posted September 9, 2012 Report Share Posted September 9, 2012 Hey.I was wondering, how easy is the connection between shadow generating function and both shadow and input function?And is Part A essential for the working solution for Part B?

macrofire Posted October 11, 2012 Report Share Posted October 11, 2012 nandhinishanmuga...if your exams are in 2010, then why do you still need to do the IA? Reply Link to post Share on other sites More sharing options...
MATHIA Posted October 13, 2012 Report Share Posted October 13, 2012 Does anyone know how to solve the last part of Part A of the portfolio...... the one where they ask u to draw a labelled diagram illustrating how the zeros of y2 may be helpful in the determination of the real and imaginary components of the complex zeros of y2...... i wud appreciate some help.... thanx Reply Link to post Share on other sites More sharing options...
