Maths Portfolio HL anyone done?? I wanted some help with Type 1 mostly, I could do Type II maybe, if I had the right software, which Im looking for Anyways, I do not know anything about the patterns in the constant and the conjectures HELP, even PM welcome

No, that is not a esterification reaxn. I meant sth else. Anyways I wanted to know the reacn conditions for these two: Halogenation of Alcohol & Hydrolysis of Halo-alkane

Lets make a list of the organic reactions with the condition people. I always get confused int the difference between conditions for esterification. Heres one, CH4 + Br2 ----UV + heat ----> CH3Br + HBr

I got that Long paper, easier than expected. Application so easy, I could do half of it. I only wish I knew there were so many questions, I would have hurried. Missed 2.

Haha, Except now, Im reading the application booklet right now. Feeling sleepy.

Physics 4, mines 41. I was wanting to know if there are some formulas in the application part ( Section B). Never got to study it. Formulas might give a few marks. Rare chance, still.

In my opinion, the graph for flux Φ is kind of the same as the one for I ( as Φ = BIL , directly proportional) and the one for EMF in the secondary is the opposite, or the invert of those above, phase difference of 180

Haha Are there many formulas in the applications part? If there are some do tell them please.

Ok, those ones are done. I dont think Ill even attempt any application though. Unless its the exact question : whats the difference between FM & AM.

whats PSTN?

Im sorry, I get it now, I was reading Tangent as Normal, Haha, Maths P3 and Physics P4 in one day !!!

Thanks for those above, In w07, 4(b), MS says direction is "tangent to curve" which curve does it mean?? Plus, why is the full-rectified graph made more straight ( ripple reduce) when Resistance is increased?

Some more questions: 1 eV = ? J And someone please explain M/J 09 9(b)

And I found, Force due to gravity = GMm / square of r Whats capacitance? Formulas associated with it that are NOT given in the booklet??
