Can anyone explain to me the first qtn how to do...do we use the "Radian" mode of the calculator to calculate or what?
then for 6 -
rad mode means not 0
second one, 6 6x4<4y<10x4 ---> 24/5 < 4y/5 < 40/5 lor -
10 is slightly more than 3pi, or ~3pi < 2x < 4pi or ~1.5pi < x < 2pi or ~270º < x < 360º

wah i completely dunno what you saying =xOriginally posted by ^tamago^:10 is slightly more than 3pi, or ~3pi < 2x < 4pi or ~1.5pi < x < 2pi or ~270º < x < 360º
siao liao tomolo test somemore

use radian mode. sin(whatever)= 3/8
find basic angle. and do the ASTC thingy.
i would do it for u...but i have no scanner at home....sry -
no1. i knowOriginally posted by unclebutcher:use radian mode. sin(whatever)= 3/8

but how abt no2. ar -
if you're in JC ,just use the GC to get your answer. if not......Originally posted by Y_Shun:no1. i know
but how abt no2. ar -
since cot(whatever)=0.
(cot (whatever) inverse)=0 inverse
thus tan (whatever) = 0
i think.
not too sure.
let me work it out and get back to u in 5 mins. -
hmm i forgot how to do liao. but for 6Originally posted by Y_Shun:

IOMGS
pai seh
i put in 1 more bracket which made the qtn more diffcutl ar...
the bracket after root 3) should be removed...this is a extra bracket. -
lemme state that clearer:
answer from basic angle and ASTC: A and B(A and T)
A+2pi, B+2pi, A+2pi+2pi,B+2pi+2pi so on and so forth till you get your 6 -
+ 2PI??Originally posted by unclebutcher:hmm i forgot how to do liao. but for 6
whats PI
i dun understand the part of 6
how we know how many rounds do we go aroung the ASTC -
PI is 3.141592654.........Originally posted by Y_Shun:+ 2PI??

you go the required no. of rounds until you get between the values they ask you for, in this case 6 -
oh so 6 is around 2 pie(assuming PI is pie
)
so we go 2 rnds la... -
ty ty..i know how to do liao after asking my math pro fren =ppp

so solved already hor? No need me to exert power anymore right?
-
think so.....wa ionic equilibria damn pain siaOriginally posted by eagle:so solved already hor? No need me to exert power anymore right? -
Don't ask me about chemistry. That one I only know how to calculate num of moles now. Last time to me very easy, now to me is GreekOriginally posted by unclebutcher:think so.....wa ionic equilibria damn pain sia -
u didnt do chem for a levels did u?Originally posted by eagle:Don't ask me about chemistry. That one I only know how to calculate num of moles now. Last time to me very easy, now to me is Greek
if i rmb correctly u did f maths c maths econs and physics...
whaha. o level chem chicken feet larh.
amaths also. especially trigo equations and proving. -
f maths c maths and physics at a levels was also chicken feet.Originally posted by unclebutcher:u didnt do chem for a levels did u?

I spent all my time on econs, using only a week for the other 3...
