that one is JC maths.Originally posted by hisoka:hmmz i thought i remember A maths got abit of complex number one leh
-
hmmz it might be weird cos you get a x^2 + 2 <0Originally posted by sammiegal:im reading the instructions!! so whatever equation that's in the square root thing should be made equal to zero or less then that. but the answer given is weird.. do i equate it to anithing??
i forgot how to do square with inequalities le hehe sorry -
-_-" wadever is in the square root, take out and put the smaller than zero. then solve as if you are doing inequalities. u know how to do inequalities right??Originally posted by sammiegal:im reading the instructions!! so whatever equation that's in the square root thing should be made equal to zero or less then that. but the answer given is weird.. do i equate it to anithing??
then the final answer u should get x > (or <) a number. that will be the answer. -

but i think the answer is everything. i mean x e R. if that makes sense. because its x square..

actually i just realised that the answer should be domain is all any value of xOriginally posted by starblue:-_-" wadever is in the square root, take out and put the smaller than zero. then solve as if you are doing inequalities. u know how to do inequalities right??
then the final answer u should get x > (or <) a number. that will be the answer. -
ahem... that one is just to tell u to consider all real values of x. but u still have to solve for the domain to exclude values of x that cannot define the function... if not all your answers is everything le...Originally posted by sammiegal:but i think the answer is everything. i mean x e R. if that makes sense. because its x square.. -
yeah paiseh never see the question properly but as long as you get the theory bahOriginally posted by sammiegal:but i think the answer is everything. i mean x e R. if that makes sense. because its x square.. -
o.O how so?Originally posted by hisoka:actually i just realised that the answer should be domain is all any value of x -
but.. that is the answer. because it can be ani value of x.. the number that is square root-ed will always be positive.Originally posted by starblue:ahem... that one is just to tell u to consider all real values of x. but u still have to solve for the domain to exclude values of x that cannot define the function... if not all your answers is everything le... -
x^2 + 2 > 0Originally posted by starblue:o.O how so?
so basically all x satisfies right? except for complex numbers -
oh yah.. me also never read question. but u know lah, for all square root questions just use the method unless it's x square.
-
x^2 + 2 = 0 isn't valid right?Originally posted by hisoka:x^2 + 2 > 0
so basically all x satisfies right? except for complex numbers
because there cant be a negative root.
darn im confused. -
where did LL go???
-
no lah your method is correct jsut that how you intepretate the inequality that you get.Originally posted by starblue:oh yah.. me also never read question. but u know lah, for all square root questions just use the method unless it's x square.
the inequality gotten from your method is correct one -
erm... for this question, x can be any value.. so just put x e R.Originally posted by sammiegal:x^2 + 2 = 0 isn't valid right?
because there cant be a negative root.
darn im confused. -
he see me say ask the 2 students then he run off leOriginally posted by starblue:where did LL go??? 
simple bear also kena kicked away by you le. maybe go hide in his cave liaoz -

the inequality gotten from your method is correct one i know lah... but lets not say more. i think we;re confusing her. -
wad two students??Originally posted by hisoka:he see me say ask the 2 students then he run off le

o.O ahh. brain overload. shall head off to bed.Originally posted by starblue: i know lah... but lets not say more. i think we;re confusing her.
thanks for the help though.
appreciated!
(none of my friends had ani idea of what i was asking cos none actually started on holiday assignments)
nights all! (this time for real
)
happy chatting. -
when i was your age, neither wud i have started on my holiday work.Originally posted by sammiegal:o.O ahh. brain overload. shall head off to bed.

night sammiegal. -
you and LL lor. you two are the only other students here what.Originally posted by starblue:wad two students??
sammie gal no probs. feel free to bring all maths questions to starblue for her to help you with 
-
actually at my age i wouldn't have started it eitherOriginally posted by starblue:when i was your age, neither wud i have started on my holiday work.
night sammiegal. -
watching this DVD of an old 1939 film.Originally posted by starblue:where did LL go??? -
im not exactly doing it by my own free will either.Originally posted by sammiegal:o.O ahh. brain overload. shall head off to bed.
