Lol aw, not fair, always getting rank 1's without even studying XDmchappypants said:I did mine on thursday last week...have no idea if it was the CSSA one. I'm pretty sure my teacher said it was bought, but I dunno where from...
If it is the CSSA one, its not too hard if you know your stuff. I got 53% with very very little study. There was no really WTF questions, time and stupid mistakes screwed my result. Not that it really matters as I'm the only one in my class so its all irrelevant except the actual HSC exam...hence the no study...
:wave: Hehe. I don't think it's CSSA, all CSSA is on Friday Ah well, good luck everyone.Chinmoku03 said:As for 4U, please let what you said be true. (ie you did do the CSSA) I'm clueless as to how I can use de Moivre's theorem in induction, but if there's massive amounts of integration and little complex, I'll be crying tears of joy (Lol melodramatic XD)
Is that even a viable question ???aricho said:Everyone ready for friday??
I can hope, don't extinguish it just like that >.<;beentherdunthat said::wave: Hehe. I don't think it's CSSA, all CSSA is on Friday Ah well, good luck everyone.
LOL. Yeah kick their asses... I can't believe that happened though, didn't the paper slowly make it's way to your class though? Did the teacher get in trouble??? *Awaits drama*mchappypants said:I wouldn't be surprised, my school's pretty retarded. For example, the Eng Adv. 2 class was given the Area of Study trial paper as practice, then they realised it was this years trial but didn't even bother changing the questions!
I was pissed as I'm in Adv 1, but the 2 class is full of idiots so I didn't protest as we'd beat them anyway...
HAHA nopebeentherdunthat said:Is that even a viable question ???
Yes, I agree. I think that it would be much easier to accept failure from now. Personally, I've become immune to failing 4unit. I've lowered my expectations to 50. I think 3 hours is perfect time to scab 50 marks...what say you ?aricho said:HAHA nope
im sooooo stuffed
haha yeah i agree i would be happy with 50%beentherdunthat said:Yes, I agree. I think that it would be much easier to accept failure from now. Personally, I've become immune to failing 4unit. I've lowered my expectations to 50. I think 3 hours is perfect time to scab 50 marks...what say you ?
For Q1, you know that a rectangle hyperbola has an eccentricity of the square root of 2. And since y = x is a symmetry axis, the rectangle hyperbola equation changes from xy = c into 2x = c. (Or 2y = c, doesn't matter) The value for x (Or y) is actually the value for "a" in a non rectangle hyperbola, so you can just use the a/e equation for diretrices. Not sure if that made sense cos I worded it badly x.x;Hikari Clover said:lol
any1 here????
1.how do u find the directrices of rectangular hyperbola???
2.when using the method of cylindrical shells to find volumes, how do u get the radius of the circle if the strips u chosen is on the LHS of the y-axis??(p.s. rotates about y-axis)
