i) by solving the equation z^3+1=0, find the three cube roots of -1

ii) let @ be a cube root of -1, where @ is not real. show that
@^2 = @-1

iii) hence simplify (1-@)^6 <----dunno understand this part


btw..this a 4u q

(1) solution:

it takes me ages..
i need to take out my digital camera(i dont have a scanner...)
and plug in the usb lines and shoot the photoes...
then i discovered my photo size is set to the largest size, so large that it exceeds the attachment file size allowance....
then i alter the size to the smallest!and i succeeded
>_<

 

[victorling]

but i dont mind

Yeah, dude, just use paint. So much easier sometimes.

lol! Just go to the 4u forum, and read the stickied thread entitled:
"notation"

Quite often it is very easy to do just about everything just by typing.

hmm, we should request laz that he put up all wierd and exotic mathematical symbols where the smilies are. thats an idea... lets think about it. Maybe its possible. Don't see why not, we can make an emoticon sized mathematical symbol, and thats it!

what "paint" are u talking about?

 

[Grey Council]

well, you buy yourself a set of watercolour paints, and a few brushes. Then you paint up the solution to problems, use your digicam to take a picture, and then post. d'oh
hehe

yep, and it seems that he's doing well- also as i mentioned on the other thread- u shuld go around answering the other "question threads" that pop up from time to time as well- then u'll get students for sure.

I think using word is even easier, with the equation editor.

Yeah, but you've got to get some diagrams in as well.

 

[victorling]

seriously
i really want to know, keypad
what paint are u referring to?
u mean the basic program in windows, that allows drawing?

 

[KeypadSDM]

Oh, I thought you were joking. Yeah, that's what I use. It's a bit longer, but it looks alot better than dogily scanned images.

 

[victorling]

lol
i was joking previously
i just guess that u might be talking about the basic program within the window
yeah, paint is pretty good, it can be colurful^_^

 

[KeypadSDM]

It can be used effectively. You can draw diagrams and use text as well. So for a free solution to writing answers on the computer, think of our old friend "Paint.exe"
