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?
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.
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...
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.
