guys , i need you to stand by me and help ,any one who's in my shoes or WAS on day,please don't hesitate to give me your advice..... i don't feel good i want to know how many marks i should lose to get an A. THANX :) :) :)
-
oh.. and by the way.. if any one has a resource about drawing the sine and cosine rules please be generous!! thanxxx a looottt!
-
Can you describe? Do you mean transformations of graphs? What module is your AS exam?
-
i mean those graphs of sine and cosine from 0 to 180 curves .those stuff you get it??
-
I will do a page on my website.
-
mai.....r u in egypt??
-
yeah
-
I 'm so tired and bored....how can maths be revised??!
-
just by solving past papers.....its very useful.....cuz math is volatile if thats the word.....studying wont offer much help....just practice the past papers...to get used to the exam format and the questions.....
P.S: r u in st.Fatima skul in cairo?? :D
-
no ,i'm in E.G.C in alexandria
thanx for your advice. :)
-
kk :D
nd ur welcome :)
-
if u have any other question or u need any help in anything.....dont hesitate to ask :)
-
i just wanted to discuss nov o8 maths pure 1( cie)
it's very hard and tricky especially the vectors question and the wire problem?! [
-
OMG my exam's tomorrow! aaaaaaaaahhhhhhhhh :'( :'( :'( >:( :o :o
-
I just hope I'm not too late
for the wire question
4x+2pir=80
r=80-4x/2pi
Area=x2+pi. r2
substitute 80-4x/2pi for r
x2+(pi X (80-4x)/2pi)2
when u open it u get
x2+ (p X 6400-640+16x2)/ 4pi2
to make denominator same
(4pi x2+ p X 6400-640+16x2)/ 4pi2
reduce...that is divide by 4 and group common terms
(pi+4)2+1600-160/ pi
for the second part
dA/dx= 2x(pi+4)x-160/ pi= 0
solve to get value of x
I will try the vector sum...but I haven't done it in class...so it will take some time
-
the as maths exam today was a hell , it had so many hard problems,it was so exhausting and mind teasing
I hope to get an A ,PLEASE GOD!
-
mai.....dont say anything about the xam to not have to remove the topic.....keep it clean.
u can discuss the exam after 24 hours....ie tomorrow
-
OOOOPS ! sorry didn"t know! ::)
-
no problem :)
so, hws life? :D
-
not fine after today's catostrophy! :'(

not fine after today's catostrophy! :'(
ohh,,k,,

What happened? You can't walk out of an exam counting up all the marks you think you lost.
-
i don't think i was counting marks i lost,but i was counting marks i GAINED! :-\
-
mr.Paul.....this xam was not pleasant.....it was the hardest math AS xam i have ever solved....not by questions or stuff, it just needs more time than it should do
-
EXACTLY!,we needed more time cuz each problem had a different and difficult idea...
hope curve is low!
-
yeah, it was terrible, wasn't it?
i'm pretty sure i lost at least 16 marks; skipped the whole trigonometry question and the part about that acute angle and tangent thingie in the last question.
balls.
-
i think you had different version cuz there was no acute angle in my exam
-
i think you had different version cuz there was no acute angle in my exam
really? D:
well good for you, i guess.
-
falafail...swearing is not allowed.....i modified ur post.....and this is a warning
nxt time will cause u getting banned.
-
nd dont discuss the xam now.....after 24 hrs u can.....any cheating will cause permanent banning.
-
falafail...swearing is not allowed.....i modified ur post.....and this is a warning
nxt time will cause u getting banned.
um, alright. :-\
i didn't notice anything about swearing in the rules, so i just assumed it didn't matter.
-
sry if it wasnt mentioned....anywayzz....no swearing :D
-
god help us in mechanics next wednesday!
-
i'm doing S1 actually D:
By the way, is M1 easier than S2? 'cause i sortof have to decide what to do this year, and i just assumed S2 would be easier, but everyone's been telling me to do M1 instead. :-\
-
M1 is not hard at all...if u practice it well and understand it..........its easier than pure 1 in my opinion
-
yeah,but sometimes there're very tricky questions,especially in friction and work,power and energy
-
"trickier" than S2, do you think? :-\
-
M1 and S1 are much easier than S2 and M2.........some ppl say M2 is mission impossible :D
i mean, dont risk it by taking S2 unless u r very gd and u r confident......but i say take M1 and S1.....thats wt ppl usually do, to get the best grades.....they dont take M2 or S2
-
yeah i'm taking s1 next year i.s.a
-
isA
-
i'm doing S1 on the 4th of november XD
it's all just knowing how to use formulas, 'cause they give them to you and everything.. so i thought maybe S2 would be similar?
oh well. M1 it is. :(
-
i dont wanna direct u to something......i dont knw hw the S2 is....im just saying wt ppl r doing.....ask about the S2, maybe u will like it better
-
oh, i'm pretty sure i won't like either of them, so i'm just going to do the easier one, hah. i appreciate your help, either way.
plus if most people are doing M1 instead of S2 then it's bound to be easier! :D
-
hahahaha......thank u for the appreciation :) :D lol
gd luck with wt ever u choose
-
guys i need help in mechanics ,i don't understand the concepts of work energy and power,
work done against friction ,pot. energy and those stuff...hope i'm not too late. :'(
-
give some questions....they may help clear ur concepts
-
how we can find work done against friction....no need to put numbers just explain!
-
here check this http://www.mathsrevision.net/alevel/pages.php?page=93
-
oh.. thank you a lot! , i also want to know if he told that total force resisting motion =60 ,this includes weight and friction resistances??
-
I didn't get ur question....
-
please people, i need specimen 2000 and june 2000 ,2001 mechanics 1 urgently i can't find them anywhere. :'( :'( :'(
