f'(x)=0 - occurs when x is a stationary point on the graph. f'(x) >0 - gradient of graph is positive . upward direction left to right. f'(x) <0 - gradient of graph is negative. downward direction left to right basically helps with the sketching of the graph, and the visualisation of the...

hello nessarhino. =) thanks for commenting on my lonerish page. >__>" btw. i think i know you from somewhere too [not stalker/pedo ; don't kill me] umm. does the name Ashley Kaing hold any significance?

a) First find the gradient of tangent to curve at x=2. y=x^2 -> y'=2x. sub x=2 into y'. y'=4. So gradient is of tangent to curve at x= 2 is 4. since normal is perpendicular to tangent, gradient of normal is -1/4 (ie. the negative recipricol) y value of curve y=x^2 when x=2 is 4. now. use...

would that combination and permutation stuff work here? because i dont think they allow for repititions. ie. doesnt allow person to get more than one award?

i think i agree with you. is the answer 8/243 but?

that was a pain in the ass to read. . . sooo yehhh. keep practising. if you get formulas mixed up , do questions that required thoses particular formulas.

multiplying/dividing by a negative number taking the recipricol of both sides. . both require you to change direction of the inequality sign.

Yeh. Its alright. Here's my suggestions. read through it again. make SURE it all make sense. its doesnt really "flow" when you describe about how hard you life was. Sometimes the sentences just drag on. Remember Quality > Quantity. there we go. thats what i personally think. believe...

clavin klein - electric.

Kfc.

FOR SECOND QUESTION. use the factor/ remainder theroem of polynomials. that is ; if (x - a) is a factor , then P(a) = 0 and for (x- a) ; the remainder when dividing P(x) is P(a) use those two results to find first 2 or so factors. then use these factor to divide original polynomial...

i played for school one season. nothing special because team was terrible. lost every game. but i was the ONLY one to have scored tries. plus i got knocked out first game, first tackle.

i know that. he's a midfielder. but guys are like: "he scores awesome goals and sets up the rest of his team all the time" as if.

David Beckham. has one or two spectacular goals. thats it.

love it. watched it for year 8 history.

(-x+5)(x-4) = -x^2 + 4x + 5x - 20 = -x^2 + 9x - 20 EDIT. ^Poster above beat me to it.

physical activity. SOURCE. my pdhpe teacher.

i dont know. pretty shoes but. =)

yes. but dont get these mixed up with funtion values.

13.5 is good for a asain nerd like myself ohkay? :haha:
