Hey Guys, This is 1A Question 24 c) of the Cambridge Math 2012 3 unit textbook: If f is a differentiable function for all real x and has an inverse function g, prove that: g'(x) = 1/f'(g(x)) Where f'(g(x)) is not 0

The question usually specifies whether it wants decimal points or degrees and minutes. Use the dot comma comma comma button on your calculator to convert.

By Coloumb's law: (Apologies I cannot write equations) The force felt would be (Coloumb's Constant*absolute value(Charge 1 * Charge 2))/distance^2 Coloumb's constant is about 8.987*10^9 (Units of NM^2C^-2 Subbing in, we get a value of about 7.99x10^11 newtons

I myself do not have experience with specifically the Penrith interview, but you want to present yourself as best as you can. Make sure a couple of things: 1) Impeccable school uniform - Ask your main office or a teacher - if your school doesn't have anything fancy like a blazer in their main...

It would either be a polygon (Assuming the cut was made straight down the prism), or it would be a rectangle if the cut was horizontal. Some information would be useful in this question, but it seems extremely vague anyway

Pretty annoyed at how difficult I found it, seeing as I put in so much effort into studying for it. Wrote an answer for everything though... The first momentum question was quite hard - understanding how each body was supposed to act and what was "Displacement" with relation to the moving chair...

Hello All, Just going into the physics olympiad in a couple of hours - and last-minute tips? Thanks!

Hello, Right now, I am in preparation for the ASOE physics olympiad, and I am in year 10. What would be an estimated score required to get into the camp stage? Obviously it varies from year to year, but if someone got in for a year, could you please post your mark? Also, how much would a year...

All schools are different, so if you give some examples of what your syllabus outlines, I can provide you with past papers. Just do the ones outlined by your school AND the exercises. Many people downplay the importance of bookwork - don't. It is really useful

The first thing is to do what you want. you've probably heard this plenty of times, so I'll get into the details here. Your subjects of modern and 4u math are quite high scaling, meaning your HSC mark doesn't need a lot of work (Still more is always better). Think about how many subjects you...

I will not present the answer here, just the explanation of how to get there. What you want to do is find any point on each of the lines. It does not matter what points you find (Think about why this may be true). Then, find the midpoint of these lines. This gives a point on the locus...

One of the big things I recommend that if you are debating, especially at a university level is to look at other debates. The major competitions are Easters, Australs, and WUDC, note these are a combination of the BP format and the 3v3. When debating, you want to make sure that you have a good...

I'm picking my year 11 subjects now, and I am unsure what exactly I should do. In year 12, I know my subjects will be: 4u Math, 2u English, Phys, Chem and maybe an extra 2 in German. For year 11, it will be the same except 3u math and some other stuff. So, my question is does taking 3 unit...
