It has been a while since I have studied galvanic cells but I can try explain it to you in physics terms. 1. Current is simply the flow of charged particles which in most cases are electrons. When electrons move in a circuit, current is produced. 2. Now that you understand that current is...

There isn't any textbook to my knowledge that has solutions to every question for the 2U course. If you find math in focus too easy or simple, may I recommend the cambridge text? Another alternative is the yellow Fitzpatrick text. I believe either of these textbooks is what you are after...

Here you go! Apologies for the bad handwriting.

I am pretty certain you dont change the mass to 1 sig fig or any part of the working out for that matter. You only leave your final answer in the lowest sig fig.

LOL....

Re: Can you get marked down in 2 unit math exam for not using a ruler or not labeling Just use a ruler to be safe. It doesnt cost much and it doesnt take THAT long to draw lines with it. Plus you get a neater diagram. But i dont think you will be penalised unless your diagram is impossible to...

Drop extension 1 maths. It will be a waste of time studying something you have no interest in. Use that time to study for other subjects you enjoy. It sounds like you enjoy ancient history so dropping it should be the last thing you should do.

May I suggest creating a wiki instead of google docs? It is far more effective when you have a good learning team.

The answer is 73 of course, why are we even considering other numbers? May I direct you guys to: http://www.youtube.com/watch?v=Gg9kSn3NRVk

This is probably the best I can find. http://www.slideshare.net/nsimmons/presentations

It is definitely (C). Probability in first turn = 4/4 = 1 Probability in second turn = 1/4 Therefore the prob is 1*(1/4)=1/4. Har, your response above is the probability of picking a 'specific' colour in both turns. The question didnt specify a colour, rather they just wanted the same colour...

I never really had notes for maths. I think people who dont have notes demonstrates that they are competent since they know their stuff inside out. Much like the standard integral sheets given in the math exam. It pains me that some students need to use the table to find simple integrals.

Here you go: P.s. Year 12 Extension kids are not encouraged to post their responses unless the prelim 2u students are stumped.

I cant but help to read the title as "Why is my name Lucas Wong?"

Unless I am mistaken, you had a little boo boo at the end.

Good question!

I thought Coroneous didnt have a phD? He only had a B.Sc and dip ed...or did you mean symbolically that he's a mathematician?

Does anyone know why Bill Pender didnt write an extension 2 text?

The biggest difference of the top of my head is that a 5 Years trained teacher will have a higher minimum salary than a 4 year trained teacher. Other factors that might influence your decision would be the ambience and quality of the uni/subject. If you just want to be a math teacher, then the...
