but doesn't it say values? which means more than one value of b? i dunno. )':

Suppose that b and d are real numbers and d /=/ (doesn't equal) 0. consider the polynomial P(z) = z^4 + bz^2 + d. For what values of b does P(z) have a double root equal to root 3i. anyone who has problems with polynomial questions are more than welcome to post here.

thanks alot for the website, you just saved my life. (:

thanks alot. is it possible to work out the solution by deriving the time first?

A long jumper left the ground at and angle of 15 degrees and jumped a distance of 7.0m. considering this result, calculate the velocity of the loing jumper when leaving the ground. please help. XD

thanks alot to the both of you. (:

Let P(x) = x^(n+1) - (n+1)x + n, where n is a positive integer. show that P(x) has a double zero at x = 1. (2008 4U HSC, Q5 b) )

P(2ap, ap^2) and Q(2aq, aq^2) are two points on the parabola x^2 = 4ay. The tangent at P and the line through Q parallel to the x axis of the parabola meet at point R. The tangent at Q and the line through P parallel to the axis of the parabola meet at point S. Show the co-ordinates of S and R...

thanks. =DD

just after launch an astronaut experiences an acceleration of 5g. two weeks earlier, at a fun park, the astronaut went around a 10m horizontal bend at 72kmh in a roller coaster. what is the ratio of the rocket launch to the acceleration at the fun park? help is greatly appreciated. =]

omg thank you thank you. =DD

Given that a string (0.6m in length), can only sustain a mass of 10kg, find the fastest speed (in rpm) that the string can be rotated (in a horizontal circle) if the mass at the end is 0.2kg? (*g is specified as 9.8m/s^2) help is appreciated!!

thank you so much. XD but i got a weird question here. it says convert 20 rpm to radians per second, and the answer says 2pi/3. i dunno, am i missing something here? >.<

having trouble getting the rpm - radians/sec process. someone help?

If a+b+c=0, show that (2a-b)^3 + (2b-c)^3 + (2c-a)^3 = 3(2a-b)(2b-c)(2c-a). please help.

LIES ajmain...-_-...you studied your butt off during both year 9 and 10 =P

only year 9s get them...-_-...discrimination...:mad1:

Re: 2008SC SC Results ~ ah wells i cant find my reserved space in this thread...lols anyways heres my SC marks just got them today >.< English: 85 :( Maths: 92 Science: 89 *insert swear word/words here* History: 91 Geo: 89 *insert swear word/words here* Computer: 90 T.T

English: Maths: History: Geography: Science: Computing: Reserved spaced for when i get my results on friday.....:jedi: (random smiley)

LOL...your school still has a MUCH better history than mine...never has a student in my school scored above a Band 6 (or maybe even a Band 5) in SC and HSC before...:lol: thats why we got pressured alot this year since we're the first selective streamed class :(
