Does anyone have the solutions to the 2006 paper? I am stuck on question 5c

Happen to come across this, might be handy for some comp 1B or comp1091 ppl http://directory.fsf.org/devel/editors/indent.html

Identify data sources, plan and perform a first hand investigation or gather second hand data for the controversy between the 2 camps of 2003 HSC physics students on the consequences of special relativity, and assess the effect of the debate on *physics*. In your description, refer to the...

1) the charge (q) held by a capacitor proportional to the capacitance (C) of a capacitor and the voltage across it (V). (q=CV) a charged capacitor is connected in series to a resistor of resistance R ohms. a) explain why dq/dt = V/R b) show that dq/dt = q/RC c) initially the...

(i) x, y are real numbers satisfying log_3[x+7] + 2*cos[y + 2003] = 4 find ( |x-2| + |x - 722| )/6 , justify your answer. log_3 is logarithm base 3. (ii) explain the significance of your answer to (i).

a>0 find the sum of all solutions for x in the close interval [-2,6] for: a^( (x^2 - 5)*|cos(x)| ) = (sqrt(a))^( |x|cos(x) )

this is from a 2 unit exam, see how many of you can do it there are 2 red, 1black and 1 white marbles in a bag. two marbles are drawn one after the other, and kept hidden in a hand. a) find the probability that that 2 red marbles are drawn b) find the probabilty that the second marble...

my careers adviser's prediction was assuring, but I don't trust him. About 10/110 in my school get over 90 every year, highest last year was 97.05, and the year before was 99.60. subject, assessment rank, trials rank, trial mark Eng(adv) (13/22) (7/22) 54% (think the class ranged from 10...

anyone have any tips? I seem to make quite a substantial number of silly mistakes...

another Kermit's problem ABC is a triangular obstacle, with AB horizontal. This time the slimy frog jumps from point A, just grazes C and lands at B. Show that it jumped at an angle of: tan^-1[tan(A) + tan(B)] to the horizontal

here's a part of a question from my trials today which I believe to be incorrect: P(x)= x^5 - 5cx + 1 Prove that for c > (1/4)^5, P(x) has 3 distinct real roots. Any ideas?

I lost my results for two pracs :( can anyone tell me their results please? solve problems, plan and perform a first-hand investigation to carry out the fermentation of glucose and monitor mass changes identify data sources, choose resources and perform a first-hand investigation to...

can anyone give an rough estimation of the aggregate required for 99+?

I asked my teacher if the following would be ok in exams, he answered: it might cost me marks. Could anyone give their opinion? given dN/dt= k(N-B) find N in terms of t. dN/dt= k(N-B) 1/(N-B) dN = k dt / | 1/(N-B) dN = / / | k dt /...

I seem to have problems setting out Mechanics solutions, I either write more than required or leave out something (eg quoted a formula, instead of deriving it :( ) are there any general guidelines, such as which formulae could be assumed.

I am quite stuck with this question P is a variable point on the ellipse x^2/a^2 + y^2/b^2 = 1 S, S' are the Foci of the ellipse. PS, PS' meet the ellipse again at Q, Q' Respectively. The tangents to the ellipse at Q and Q' meet at R. Find the locus of R. So far I can only get up to R...
