I dont get the 3rd one O_o ...all u did was to prove 0.(9)=0.(9) which is obvious (and I didnt get the proof either).For me,0.(9)=1 as the 1st proof.
Btw,u on W3XBnet Forum? =p
Err...Arg(w) still increase faster than Arg(z).Can we use limit of lzl since z can be as close to z=2 as we want?
Btw,do we need to write all these things or just sketch it?
Thx.
Re: Re: Math1901
u mean a circle with x-intercep +/- 4 and center O(0;0)?
Its not right coz it didnt cover the case where lzl<2(hence has mostly invalid pts)
If u shaded the thing then u ll have too many extra pts coz for any modulus of z theres only fixed 1 Arg(z).
Did u guys do the assignment?What you got for 1b?-Its impossible to find the equation so I did tracing and got a Heart O_o...???
Btw,this s the question:
a/ sketch lz-1l=1
b/ sketch w=z^2
1st-prove it a parabola (let z=x+iy) y^2=4a(x-a);
2nd-differentiate the parabola equation -->equation of tangent through O :y-y0=2a/y0*(x-x0)
sub x=0,y=0 u got 2 tangent with make with Ox angle of +-(pi)/4 .
3rd-The parabola lie inside angle made by 2 tangents
ie larg(z)l<= pi/4
They've changed the law so it would be really hard to apply oversea.
At TAFE ,I can get eCOE before 31/12 to extend my stay.
well, i suppose thats all 'bout it.
Well,I dont have to wait for my UAI anymore(altho I expected it will be at least 90+).My Visa will end at 31/12 and I wont have offer until 5/1 therefore cant extend it in time.Now I am left with only 1 choice: study TAFE(or go back to my home and never have chance to come back) ,wow,how fair is...
:p anything at its high oxidation No. is a strong oxidant especially those with high and moderate electronegative eg:ClO4- coz they simply cant "give" any more e :p
for those like CrO2 it may be becoz most of its electron has been attracted to O atom thus the Cr atom appear "possitive" thus...
