bump again...not answered ;)

bump for more replies xD Gna go do work soon...and still cant get the right answer x = y/3 x^2 = y^2/9 x^3 = y-2 x^2 = (y-2)^(2/3) V = pi integral 3 and 0 y^2/9 dy - pi integral 3 and 0 (y-2)^(2/3) = pi [y^3/27 - 3/5(y-2)^(5/3)] between 3 and 0 doesn't get me the answer i need :evilfire:

incorrect. when x=1, y=(1)^3+2=5 already wrong. answer is 2/5 pi u^3. Lol i know the steps, its just that i dont get the answer.

lols xD i made a few answers in super brief summary, they're not even sentences. :D You don't really need to know the history, just the main ideas, such as what materials you use, why, is it cost effective etc. Give me the maths questions you are stuck on and i'll see if i can help ;)

hehe you're suppose to find V, it does not equal to 2000

there was individual parts so i tried to simplify it. I dont know where to take the integral of a and b at. This is the whole question 1) Find the equation of the tangent to the curve y = x^3 +2 at the point where x= 1 2) draw a diagram showing the region bounded by the curve, the tangent and...

y = x^3 + 2 y = 3x Region bounded by the curves and the y axis. calculate the volume of the solid generated when this region is rotated about y axis Intersects at (1,3) and (-2,-6) blonde moment maybe :mad:

what'd you do at step 4 (second last one)

i wouldn't rely on someone to use "you're" instead of "your" to tell me that my grammar is such. Though i do admit my grammar is sucky.

in my opinion, god does not exist. I believe it is a creationism of human kind in order to avoid the ultimate question of life. i.e. providing a conjecture with no proof whatsoever, leaving only belief in individuals. By providing an alternate answer, since one is not definite to "what/who...

oh yeah you're right, it's just a turn at (-1,0) my bad

topped it as in 1st in state?

lol you know i actually saw this but couldn't be bothered subbing it back in to check xD thanks anyways :D

-exam papers -teacher's advice -the one's who don't ask questions (when they don't know) are the ones that are truly dumb -good sleeping periods -preparation -balance -quality over quantity (understanding not amount of info which you absorb) -try to beat your friends, whilst allegedly...

no not all the time o-o just when im bored and too tired for anymore work

lmao the gay thing is we have to follow what he does. so can't like avoid doing his shit ass questions. a 2 min question and gives us a period. greeeeatt no theory or teaching before it and tells us to do a question we never learnt before...hoooorrraayy. hmm 1600...top 50 in state is beating 97%...

umm thats not really my question :P (1 + 3w + w^2)^2 = >>>>>(-w + 3w)^2<<<< = (2w)^2 = 4w^2 (1 + w + 3w^2)^2 = >>>>(-w^2 + 3w^2)^2<<<< = (2w^2)^2 = 4w^4 = 4w where does he get this. Probs another method but dno what it is :spin:

here ya go read up Water Conductivity and Dissolved Gases

rofl dw got it now LOL but dont get where you obtain (-w + 3w)^2 from i just did since (w^2 + w +1) = 0 (0+2w)^2 = 4w^2 same for the other one
