N2O also in fertilisers (organic matter). NO combustion of engines. CO2 respiration. SO2 = volcanoes and metal extraction

I have no idea what you're talking abt when refering to field diagrams :spzz: If you're talking abt the measurements of a field i can help, though an actual question on it would be better. Field diagrams as in l x b = A ?:confused: Like i said, an example would be best.

Belonging can challenge an individual if they do not or cannot conform. Belonging is a very fluid feeling as it can change over time, meaning that it is not fixed. Through this speculation, one can see that it may hinder one's sense of belonging i.e. failure to belong to a group of people...

how do you tell if something is in compression or tension for trusses.. that shiet effs me up. from what the teacher said i remember it is going away from joint is tension going to the joint is compression. Though i merely understand that, how do you know where the force is going :argue:

5 periods a fortnight. Finished just complex last year. 1 lesson on graphs , 1 lesson on polynomials xD Though was given full solutions to cambridge book for graphing to complete Took me like 1 1/2 weeks to finish :apig:

firstly graph y = 2x (linear function) then graph 1+x^2 (parabola with vertex (0,1) Through translation of graph do 2x / 1+x^2 then you have some graph looks like an oblique parabola thing (just guessing didnt actually do it) now you graph y = e^x (just the basic graph going at y>0 and touches...

\frac{3-2\sqrt3}{3+2\sqrt2} + \frac{3+2\sqrt2}{3-2\sqrt3} = 9-6(\sqrt2+\sqrt3) + 4 \sqrt6+\frac{9+6(\sqrt3+\sqrt2) + 4\sqrt6}{-3}

\frac{3-2\sqrt3}{3+2\sqrt2} + \frac{3+2\sqrt2}{3-2\sqrt3} = 9-6(\sqrt2+\sqrt3) + 4 \sqrt6+\frac{9+6(\sqrt3+\sqrt2) + 4\sqrt6}{-3} i swear equation editor is hard to use!!! i cant freaken find the signs LOL Rationalise them both individually then simplify just common denominator...

2hrs to spare for the exam? O_O meaning you practically finish it within an hr or so What i tend to do is look at how many pages there are first and the time limit which restricts the amount of info. If i believe i can finish it in time with excess info, i'd go for it, but if it seems too long...

55 per hour is some crazy shit o-o I think doing pure exam style questions put you to sleep. So half half would be reasonable. It's really up to what you prefer as it is 1 on 1

lol thats exactly what i said. The OP probs didnt type the whole question, so i gave him an example in which he could base his understanding on :D

Dw question answered. If you wna know the solution put a post here :pirate:

13a) This is from what i remember >>> i've forgot this so it may not be 100% x^2 = 4ay since the equation is x^2 = -2y a = -1/2 Therefore you have points (0, -1/2) and (4,-8) two point formula: -8 + 1/2 / 4-0 = -15/8 (gradient) y + 1/2 = -15/8 (x - 0) y = -15/8 x - 1/2 I think this is...

Hmm thats the exact same question i had in my exam O_O

I have a temptation to paly now xD But i cbf installing it.. thats maybe one way how you can quit. I dont really play any game, and i hope not to during my HSC. In yr 10 i was pretty into it ;) LOL in engineering our teacher was aaway for a month, all we did was warcraft during HSC ==" FKN FAIL...

ROFL I DONT WANT 400 PAGES OF INFO YOU CRAZY? id prefer summaries which i can remember fast and with ease I'm gna go check resource section now ;) I swear if i get a mark of < 85% im gna quit engnineering. eff it.. The teacher is like omg. Just gives a question with no answer on teh board, dno...

Hey my school is using the book by Copeland and my teacher barely covers ANYTHING. I'm serious we do one question that takes 2 mins and then he just expects us to come up with an answer after 50mins. Sometimes we even get questions that we never ever done before, and he expects us to do it...

A 4-wheel drive vehicle which can average 40km/h and 110km/h off and on the road respectively, is 30km from the nearest point N on a straight highway. Which direction should the vehicle take to reach town T, 100km along the highway from N, in the least time? How long does the journey take? By...

lol yeah that seems correct. Last year the results of the raw marks were quite low, meaning that the test was hard. Really depends on the difficulty of the test ;)
