well, i thought just the intercepts, the general shape...and thats abt. it- just like the curve skecthing from 4u.

i've drawn a sketch for 1b- can someone tell me if this looks right??

cheers

Er..I think u miss out the maximum pt which is real(w)=3/2 and vertical tangent too ^^
Btw,any1 having 1902 at 8 tomoro?

thanks for the reminder MyLuv, i was living in a dream there for a while.

yeah, i thought that the maximum will have a negative x coordinate...hmmm...so i just change that to positive right?? and also - what do u mean abt. vertical tangent?

yeah, i've also got 1902 lecture at 8 2moro.

MyLuv - you just need to sketch it.

Freaking_out - your sketch is the correct shape, but you have shown the max somewhere in Re(w) < 0, when it should be in the region Re(w) > 0.

How do I know? Well, the point z = (3 + i * sqrt(3)) / 2 lies on the circle, so w = z² = (3 + 3i * sqrt(3)) / 2 should be on your sketch. This point has Re(w) = 1.5 and Im(w) = 3 *sqrt(3) / 2 = 2.598..., clearly above (on the imaginary axis) the intercept at w = 2i.

So, your curve should be increasing as it crosses the imaginary axis, rather than decreasing. Otherwise, it looks OK.

I haven't actually figured out where the max is, so MyLuv may be right about its position, in which case the point I just chose at random happens to be the max - what a coincidence!

okiez then- i will change that, but i got confused when myluv said something abt. "vertical tangent"- is he talking abt. the one at 4?

btw myluv- if u wanna meet up wif us BOS'ers- look for this retard on tommorow's maths lecture.

what do u mean- like did u forget the maximum or something?

No, he's talking about the one for Re(w) < 0

yeah, but didn't i show that there is a vertical tangent- or do i have to make it look more apparent?

no i was just pleasantly deluding myself that i didn't have an 8 o'clock lecture tomorrow

You have shown it is present - if you want to go further, you'd need to find where it is...

yeah, well look for the retard on the picture above, and then u can meet us ppl. from BOS.

 

[KeypadSDM]

Screw you, I'm not a retard.

You're the one who needs to ask questions for the assignment

 

[Collin]

Oh shit, I totally forgot about the assignment. Fuck. It's due on Tuesday too isn't it?

Self-pwned.

 

[MyLuv]
