When do the lecture slides get uploaded onto utsonline? I always thought it would be at least a day before so i can print and take notes on them...but it seems to be like an hour before or something...so i can't print it before the lectures

2U - integration 3U - integration, loved everything else 4U - integration, but liked the mechanics topic, too bad the 2012 HSC had no decent mech qs =(

To Carrotsticks: The reflection property of the hyperbola was there =)

Can anyone show me how to solve these questions?

Can anyone explain how to do these types of graphs? F(1/x) F(x^2)

please help solve:) integrate: by substitution: 1) dx/(x sqrt(x^2-4)) [x=1/u] 2) dx/[(a^2-x^2)^(3/2)] [x=asintheta] 3)(e^2x)dx/(e^4x -1) [u=e^2x] 4) cosx dx /(1+sinx)(2+sinx) by parts: 1)cos^4(x) 2)x(inverse tanx) 3) log(a^2+x^2) and....write as partial fraction: 1/(x^4 +1)...

This year, my english teacher left the school and so now we have another teacher. The problem is, she doesn't seem to know much about the english course. We've done frankenstien and speeches with her. For frankenstein, she just got us to read parts of the book every lesson, then watch...

Please help solve. The sheet they come from didn't have answers =( Integrate: 1. (2x+3)/sqrt(x^2+2X+3) 2. (5t^2+3)/t(t^2+1) 3. sqwiggle thing root 3 and -1 (definite integral): X^2/sqrt(4-x^2) 4. (3x^2 -8x^3-19x-14)/(x-3)(x^2+2) thanks people

Those usual book stores. Have you checked Dymocks? I've seen its there before.

1)Find general solution: sin 3x = sin 2 x 2) Graph |x|-|y| = 1, explain.

Solve for z and w: 1) (2+i)z+(2-i)w=1 and (2-i)z+(2+i)w=2 [ans: z=(3/8)+(i/4) w=(3/8)-(i/4) ] 2) z+(1-i)w=2i and w+(1-i)z=1 [ans: z=1+i w=-1] thanks

yay!!! thanks, it helped =)

alright... i'll use my brain...and giving it a go... 1. I-beams are I shaped because something about having more volume, hence strength in the top and bottom where the bending stresses are the greatest. So holes are cut to.....reduce material?. Structurally okay because....less stresses...

1. In I-beams, why is it structurally acceptable to cut holes into the web but not into the flange? Why are holes cut? 2. A galvanized steel post is anchored to concrete by zinc cobalt coated bolts. Why are the nuts on the bolts significantly more corroded? 3. Shear Force and Bending Moments...

1. Find the equation of the ellipse with centre the origin and foci at points (-5root3,0) and (5root3,0), given that it passes through the point (8,3) Ans:x^2 +4y^2=100 2. P is the point (acostheta,bsintheta) on the ellipse E: [general form of ellipse eqn] with eccentricity e and foci S,S'...

For me, I would really like to take a break but I have three assignments as well as homework from most of my subjects due over the holidays. Anyone else in this situation? but its still hooliday coz i do nothing in the evening. So i guess its just, take a break and study if you've fallen behind...

Do you recommend them because you own them? Please tell me you do coz i really need help on some of the mechanics questions =( (makes it easier to ask)

E.g. "Suggest a service property and an engineering property of wood as a roof beam"

Can some one explain the difference between those two? examples? confused...Thanks

If its time, dropping IPT is 2 units while 4u is 1 unit. and maybe i will work harder with 2 less units for 4u. or is it the same, cause 4u is like 2 units worth of work?
