Re: MX2 Integration Marathon Let u= x^(n-2) du = (n-2)x^(n-3) dv = x^2 (sqrt(1-x^3)) v= -(2/9) (1-x^3)^(3/2) Un= (-(2/9)(1-x^3)^(3/2)x^(n-2))_1_0 +(2/9)(n-2) integral_1_0 ((1-x^3)^(3/2)(x^(n-3)) = 0 + 2/9 (n-2) (2/9)(n-2) (integral_1_0 ( (1-x^3)^(1/2))(1-x^3) x^(n-2))) =(2/9)(n-2)[ integral...

Re: MX2 Integration Marathon e^(4/9) ? Looks way off.

And the conical flask conventionally contains the standard solution as far I was taught.

It doesn't matter. As long as you get the stoichiometry right. But personal preference, if one of the solution like NaOH absorbs moisture then use that in the burette as it can be covered by aluminium foil.

These.

There we go growth and decay.

Wait doessnt that come in I2I? Oh if this helps lemme clear it: P (transmitted)=VI is the formula that shows the initial relationship between power transmitted. Note: This is not the power lost. So you can calculate either of the quantities from this. Then but V(drop)=IR and note...

Re: HSC 2014 4U Marathon Volumes Question :

Re: HSC 2014 4U Marathon - Advanced Level Hmm... Why do I have the feeling that you are talking sum of roots as 20/16 and not 0? This may justify the negative one possibly?

Congrats Nice Ranks! Agreed with ObviousNinja

That doesnt help. She is from a top 20 School. Certainly. Ranks change quickly and 1 % change can put you up 20 ranks and vice versa so put a little more effort and you will be good to go. And plus your school is in top 20 so even if you get in the 20-30's rank range for them thats still a...

Prioritize respectively: 1) Weaknesses 2) Units 3) Interests You might just be able to identify and consider what competition can lead to from real life experience. To answer your question, HSC sciences are about rote-learning, so as long as you can completely rote-learn each and every important...

Dunno. Not that important anyways- except the last meeting farewell. Probs public transport unless i get my P's.

soccer

congrats on great results. keep it up.

Re: HSC 2014 4U Marathon Let x= a^2sin^4 (theta) you get ln (sec theta)-(sin ^2(theta))/2. then use the right angle triangle to find x values and sub them in for theta. Dont know how to use latex sorry.

New school, it happens. Why is it so that you have to drop MMX1 to drop EMX1?

Yes. How about transfer?
