it is alright
i will post all 3 parts
i will post all 3 parts
(1) solution:Originally posted by ToO LaZy ^*
ok here's one..
1.
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

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

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.Originally posted by xiao1985
well, he's takin up freakin_out's advice and start helpin pplz before tryin to get any more students i fink... ^^
I think using word is even easier, with the equation editor.Originally posted by KeypadSDM

Yeah, but you've got to get some diagrams in as well.Originally posted by J0n
