Ongfufu Posted March 8, 2009 Report Share Posted March 8, 2009 If your teacher won't give you a book, go buy your own. Or, if you have BitTorrent, I've found this torrent that has the entire Haese & Harris HL book in there. http://btjunkie.org/torrent/IB-Math-Higher...da5041ba7b1a362 Download at your own risk, beware of viruses.

CocoPop Posted March 8, 2009 Report Share Posted March 8, 2009 The second derivative can be used to find non-stationary points of inflection, which the first derivative can not do. Reply Link to post Share on other sites More sharing options...
LinuxBeta Posted March 8, 2009 Report Share Posted March 8, 2009 If you still need the book, someone in HL scanned the book for the SLs. If you still need it, let me know and I'll forward you to someone who has it. Reply Link to post Share on other sites More sharing options...
Tarz Posted March 9, 2009 Report Share Posted March 9, 2009 Thx Spider. Our test is postponed now... I think I just lost interest in reading that book... lol jk. I'll still do it. Reply Link to post Share on other sites More sharing options...
Tarz Posted March 15, 2009 Report Share Posted March 15, 2009 I'm studying for a test and I came across this. I don't understand how to solve it.For a) I get as far as knowing that y=-x has to be tangent to y=1/2 x^2 + c, but I don't know how to solve that.I think the derivative of y=1/2 x^2 + c has to be the same as the derivative of y=-x... so y=x and y=-1 so x=-1. That's where they intersect. But how do I get C? (-1,1) is where the two lines intersect... so that's a point on y= 1/2 x^2 +C. So 1= 1/2 (-1)^2 + C has to be true. So 1= 1/2 + C. C=1/2. LOL WTF I SOLVED ITWell, does anyone know an easier way to do this? Reply Link to post Share on other sites More sharing options...
deissi Posted March 15, 2009 Report Share Posted March 15, 2009 If it makes you feel any better, it's not an IB-style question, and you'll never see anything like this on an IB exam. Reply Link to post Share on other sites More sharing options...
moneyfaery Posted March 15, 2009 Report Share Posted March 15, 2009 Same process for the other questions. Why is this thread funny, btw? It's a good thing that OP wants to improve his/her math skills. Reply Link to post Share on other sites More sharing options...
Tarz Posted March 16, 2009 Report Share Posted March 16, 2009 I can't download. But yeah, I guess it's not an IB style question.What about this one? This one I'm actually confused about... It's in the anti-derivatives section, so it should be solvable without actual integration. It's referring to the distance, not displacement, which I don't know how to find.

Hedron123 Posted March 17, 2009 Report Share Posted March 17, 2009 Ok, you cannot solve this without integration. Velocity is the variation of displacement in time:velocity = distance/time. The derivative of distance/time (delta distance/time) results in velocity while integrating velocity results in displacement.You know that when t = 0, the object does not move as velocity is also 0. You have to integrate the function between 2 and 0 and between 2 and 3. and add both values to solve the exercise. 1st) Integrate the function:the integral is: 3t^2 - t^3 + cIf you integrate the function between 2 and 0:3 (2)^2 - (2)^3 + c= 4 + c3 (0) - (0)^3 + c = c4 + c - c = 4.When integrating the function between 2 and 3:3 (2)^2 - (2)^3 + c= 4 + c3 (3)^2 - (3)^3 + c = 0 +c4 + c - c = 4.Hence: 4 + 4 = 8.

Leeeeeeeeeena Posted March 17, 2009 Report Share Posted March 17, 2009 hey guys,does anyone of you own older mathematics exam papers by chance (in a pc copy?) ? Reply Link to post Share on other sites More sharing options...
Mahuta ♥ Posted March 17, 2009 Report Share Posted March 17, 2009 Hey there,You wouldn't really find them on here.There are many websites that have them though Reply Link to post Share on other sites More sharing options...
Ongfufu Posted March 17, 2009 Report Share Posted March 17, 2009 Mahuta, I thought we weren't supposed to post these links here, since IBO will find out and shut them down. At least one of the admins told me that last time I posted these sites. Reply Link to post Share on other sites More sharing options...
Leeeeeeeeeena Posted March 17, 2009 Report Share Posted March 17, 2009 well, I didn't ask you to post them - just whether someone had any. Then I would think of a legal way to obtain them I think there aren't any webpages left. at least none I found. only matematics HL or maths studies.

faerie Posted March 23, 2009 Report Share Posted March 23, 2009 Okay I'm not sure if you guys have a copy of the May 08 Math SL mock test, but I have to do it for homework, and I don't understand what one of the questions is asking! #4 says "differentiate each of the following with respect to x" and it's like y=sin4x, y=xtanx, y=lnx/x. help please? Thanks! Reply Link to post Share on other sites More sharing options...

Ashika Posted March 23, 2009 Report Share Posted March 23, 2009 (edited) What the crap??Honestly, you SHOULD know how to do that.It means find the derivative of those functions.Surely you know that?ps: hehe, that was my exam.
