hey guys, having trouble with this one: y=x + 4/(x-1) i have found 1st and 2nd derivatives. Minimum turing point at (1/2, 15/4) and there are no points of inflexion. there is an asympote at x=1...right. This line is more than just that though isn't it? how can u tell that you got...

Hey everyone, just wondering if there is any way that price elasticity of demand and supply can be measured in the sharemarket? thanks for your help

" the height "h" meters of a cricket ball after being struck by a batsman is given by the equation h=1+x-(x^2/40) where x meters is the horisontal distance traveled by the ball from the bat. how far would the ball travel before it hits the ground?" I have: using pythagoras...

Hi, i'm stuck with this question, I'm prob missing something easy. the "c" above middle c on the piano has a frequency of 512 Hz. calculate the wavelength. Thanks for your help

hi, i was wondering why the sine function makes a squiggly line on the number plane. i know its not the right terminology so sorry for that. thanks

is that it? i did y^2-x^2=36 (x-y)(x+y)=36 (x-y)(8)=36 x-y=36/8 is any of that correct?

Hi, i just sat my maths exam, and i had a very strange question... i don't know how to do it... x+y=8 x^2-y^2=36 find the values for x and y Thanks

yer, but how can u prove that they triangles are similar?

I'm having trouble doing this... prove triangle PQS is similar to triangle QRS Hence prove QS^2=PS.SR the diagram is attached cheers

your not supposed to have a square root on the bottom are you?

fermat is correct the plusminus 2 belongs to the root 2

hmmm, maybe the answer is wrong... it says {2(9x^2+4)}/(3x-2)(3x+2)

is that with a plus in between the fractions?

nice...it does...how about it with a plus instead of a multiply between the two factions

how did u get there?
