dessskris Posted November 27, 2011 Report Share Posted November 27, 2011 wrong darling, for your L2 you should've put 3, 6, 10 and 15 ONLY and put n from 2 to 5 only. you can't assume that the numerator is 0 for the first line. it's obviously wrong anyway, if the numerator is 0, the number will be 0 instead of 1.

hehe_lalalala Posted November 27, 2011 Report Share Posted November 27, 2011 OH....that's embarrassing. $: Thank you! Reply Link to post Share on other sites More sharing options...
hehe_lalalala Posted November 27, 2011 Report Share Posted November 27, 2011 (edited) OK SO. I'm getting a quadratic regression now but it's not passing through any of the points....is that what others got, too? EDIT: Also, should I include all my mistakes in the portfolio, as part of the process...? o_o I've made many, I'm pretty much starting over again..

dessskris Posted November 27, 2011 Report Share Posted November 27, 2011 haha how come? your points should be (2,3) (3,6) (4,10) (5,15) and you should get a nice quadratic curve that perfectly fits.remove all your mistakes, mistakes will only lessen your grades.

hehe_lalalala Posted November 27, 2011 Report Share Posted November 27, 2011 ...WOW I feel really dumb, I typed the equation wrong when I graphed it. So sorry! Yeah, the curve fits perfectly, thank you so much! Reply Link to post Share on other sites More sharing options...
hehe_lalalala Posted November 28, 2011 Report Share Posted November 28, 2011 I found a gs for the denominator, but it's not giving me the right results.. Reply Link to post Share on other sites More sharing options...
razgriz_!10 Posted November 28, 2011 Report Share Posted November 28, 2011 Took me three hours to do it...but I've finally got the answer.It's such a lovely question because once you do solve it, you realize why its named LACSAP's fractions...

URA BOAT Posted November 28, 2011 Report Share Posted November 28, 2011 i got the answer but i still dont get the name...maybe if only the thing that if you read it backwards it spells pascal as in pascal triangle....but i saw that when i got this assignment!?!?!

Buckeye Lover Posted November 28, 2011 Report Share Posted November 28, 2011 Okay, so once I plot En(1) against n etc., how am I supposed to use the graph? Reply Link to post Share on other sites More sharing options...
orange17 Posted November 28, 2011 Report Share Posted November 28, 2011 hey this really helped me thx everyone. I just wanted to know, Desy Glau, how do you make that awesome spinning like crazy smiley face thing Reply Link to post Share on other sites More sharing options...

dessskris Posted November 29, 2011 Report Share Posted November 29, 2011 YO ARSLAN !! how do i find it . i am have a hard time. its amet ! .. I found the equation for the numerator ! but how do i find the equation for the DENOMINATOR ! I tried plotting 1,2,3,7,11,16 with - 1,2,3,4,5,6 BUT ! but how do i find the equation of that ? .. and what should i plot it till ? the E(4) . PLEASE HELP , its due tommorrow and i dont have anything ! why do you have 1? the denominator for the 1s at the edges is not 1 you know. remove the 1 and you'll get the right answer. till you have at least 5 different equations. (Edited) - i found 5 equations, but they are not nice numbers ? they are in decimals.. now what ? how do i generalize them ?? am i doing it right ? i found equations that look like -- ( RANDOM NUMBERS ) 0.21212x^2+0111x+2.1111 ! what do i do with these 5 equations ? PLEASE HELP ! you did it wrong because you included a 1. I found a gs for the denominator, but it's not giving me the right results.. you must've made a mistake. if you want me to go through it to point out your mistake, message me and I'll give you my email address. when's it due? Took me three hours to do it...but I've finally got the answer. It's such a lovely question because once you do solve it, you realize why its named LACSAP's fractions... CONGRATULATIONS!!! ahaha I don't really get why it's named lacsap's tbh except because the pattern in each row is reversed. mathematically, no I don't see why. could you enlighten me? message me, perhaps? for the sake of my knowledge Okay, so once I plot En(1) against n etc., how am I supposed to use the graph? find the regression. hey this really helped me thx everyone. I just wanted to know, Desy Glau, how do you make that awesome spinning like crazy smiley face thing glad to have helped! ahaha, though it seems that you've figured it out, in case if anyone else is wondering the code is : panic : without spaces like 1 Reply Link to post Share on other sites More sharing options...
hithere Posted November 29, 2011 Report Share Posted November 29, 2011 Could someone help me with the technology part of my portfolio? it's the lascap's triangle investigation, I have no idea how to put technology into it other than with GDC regression and excel graphing, which is not enough. My teacher says to use things on the GDC that we haven't learned yet, if you know please just point me to the right direciton, i am not asking for answers. thank you.

anoceanapart Posted November 29, 2011 Report Share Posted November 29, 2011 can anyone give me clues for the scope and limitations part of the portfolio? what is the difference between scope and limitation? Reply Link to post Share on other sites More sharing options...
El Che Posted November 29, 2011 Report Share Posted November 29, 2011 It basically asks for which for what values of r and n the general statement would not work. Consider this: Can r and n be negative, rational/irrational, real numbers? 1 Reply Link to post Share on other sites More sharing options...
anoceanapart Posted November 29, 2011 Report Share Posted November 29, 2011 ^ so would that be the limitation or scope? Reply Link to post Share on other sites More sharing options...
anoceanapart Posted November 29, 2011 Report Share Posted November 29, 2011 do we need to use matrices in order to get a good mark?or is the simply use of quadratic regressions just fine..... Reply Link to post Share on other sites More sharing options...

My teacher says to use things on the GDC that we haven't learned yet, if you know please just point me to the right direciton, i am not asking for answers. thank you.all I can see that can be used in this paper is just regression and graphing. there's no other way that I know of in which we could use the calculator in the development of the task. sorry for not being very helpful! perhaps if your teacher could give you more hints (what you use it for, in which part, what feature that is) I could help you guess the feature.do we need to use **** in order to get a good mark?or is the simply use of quadratic regressions just fine.....graphical method is totally fine since it's an SL paper, but if you want to get full marks or to amaze your teacher, well go for a more mathematical method like what you mentioned.

Dreamzman Posted November 30, 2011 Report Share Posted November 30, 2011 FOUND THE ANSWER ! THANKS ! ! i plotted without 1 and got it ! it was hard generalizing it , i had to think it thru ! BUT I GOT THE ANSWER Reply Link to post Share on other sites More sharing options...
Dreamzman Posted November 30, 2011 Report Share Posted November 30, 2011 i have one concern ! I did everything , i even found the equaiton of the denominator, but what do i put for En®= ? Reply Link to post Share on other sites More sharing options...
