Vicki Posted November 3, 2011 Report Share Posted November 3, 2011 So... What did everyone think of Paper 1? Reply Link to post Share on other sites More sharing options...
feba Posted November 3, 2011 Report Share Posted November 3, 2011 Paper 1 perhaps had a little too much calculus for my taste. I would have preferred trigonometry and probability, especially for Section B. Overall, I think it was a bit harder than the papers I had used for practice, but I didn't do it that bad either. I was a well-done paper, not what I expected, but I proved that I knew the course.My guess would be that I'm up for a 5 in Maths SL, maybe 6.

Ezeh Posted November 3, 2011 Report Share Posted November 3, 2011 I actually was pleasantly surprised. I found it to be pretty easy, but that's maybe because I much prefer calculus over any other topic. Just a quick question to everyone: With the question containing the equation in the form - Did anyone else notice that there was an extra set of brackets inside the sine function? Was I wrong to expand it out? Reply Link to post Share on other sites More sharing options...
ChikkyD Posted November 3, 2011 Report Share Posted November 3, 2011 I thought it was really hard :/ I was so uncertain of so many things. Harder than all the exams I did for practice, and I went right back to 2007. Sad ChikkyD is sad Reply Link to post Share on other sites More sharing options...

ChikkyD Posted November 3, 2011 Report Share Posted November 3, 2011 I don't know, just everything I'm really not that great at maths to begin with. And there were no 'give-away' questions like Series and Sequences or stats. I guess I could have studied a little more.. but I've always been much better at Paper 2's than 1's. At least it only counts for 40% Reply Link to post Share on other sites More sharing options...

Ended up running out of time and not being able to complete a 6 point question (the last bit to the sine/cosine graph question) Reply Link to post Share on other sites More sharing options...
ChikkyD Posted November 3, 2011 Report Share Posted November 3, 2011 Yeah, section B was just ridiculous :| the last question was horrible. I'm really just hoping for a pass right now, let alone a 5. Reply Link to post Share on other sites More sharing options...
Peanut Butter Jelly Posted November 4, 2011 Report Share Posted November 4, 2011 What was the last question? Reply Link to post Share on other sites More sharing options...
poppyseed Posted November 4, 2011 Report Share Posted November 4, 2011 I don't know, just everything I'm really not that great at maths to begin with.

At least it only counts for 40% I completely agree with you, ChikkyD. I came out of Paper 1 thinking "oh crap". My maths teacher came and patted me on the back saying "Don't worry, you still have tomorrow!". I have consistently done better in Paper 2, and I thought Paper 2 was a lot more approachable that Paper 1. I would love a 4 for maths... I've been struggling all year.

Lewis Tan Posted November 4, 2011 Report Share Posted November 4, 2011 yeah... i messed up the sine curve thing a bit because i thought it was a negative amplitude.i had never encountered the tan 2 theta question either, nor the second part of the discriminant question where is was like -5<x<5 equal probability... did not get that.the last question also it was a bit of a guess, because i never derived the fraction thing into a ln b. i think i just went 90 ln 4 or something. um... yeah hopefully i did ok. the rest of the questions were straight forward and easy Reply Link to post Share on other sites More sharing options...
Ezeh Posted November 4, 2011 Report Share Posted November 4, 2011 The last question involved integrating into the form to get a final answer of And the final question of that section was really quite difficult, but in the end I think I deciphered it - you needed to simply add (or your answer to the previous question) to the 120 that it gave you 1 Reply Link to post Share on other sites More sharing options...
Gee :) Posted November 4, 2011 Report Share Posted November 4, 2011 I was just happy there was a section B question I could answer (vectors ) . Compared to all the other paper ones I've done,I thought it was really good. However,I was in the minority.Most of my class hated paper one.

JenRice Posted November 5, 2011 Report Share Posted November 5, 2011 Why wouldn't you need to expand it? Isn't the general form ? The general form is y= a sin b(x-c) + d which can also be written as y= a sin (b(x-c)) + d so expanding it wasn't necessary. Reply Link to post Share on other sites More sharing options...
Ezeh Posted November 5, 2011 Report Share Posted November 5, 2011 To find what the value of c was. So the value of c wasn't the horizontal translation (2), therefore you need to expand out first to get 2=bc, therefore c=8/pi? Reply Link to post Share on other sites More sharing options...
Vicki Posted November 5, 2011 Author Report Share Posted November 5, 2011 Yeah, I think so Why wouldn't you need to expand it? Isn't the general form ? The general form is y= a sin b(x-c) + d which can also be written as y= a sin (b(x-c)) + d so expanding it wasn't necessary. That's what I did.. I just left it Reply Link to post Share on other sites More sharing options...

I've been mistaken all along and after thinking about it logically it makes sense Reply Link to post Share on other sites More sharing options...
