Re: Several Variable Calculus Consider the two metrics d(\mathbf{x}, \mathbf{y}) = ||\mathbf{x} - \mathbf{y}|| and \delta(\mathbf{x}, \mathbf{y}) = \frac{d(\mathbf{x}, \mathbf{y})}{1 +d(\mathbf{x}, \mathbf{y})} (you may assume they are metrics). i) Show that d and δ are not equivalent.

I got arctan((3g-4)/(sqrt(3)*g)) and I said since what is inside the arctan is positive, due to g being negative, that the acute angle is positive.

If, for question 14 b ii I wrote t as a function of x, but in b iii I made x the subject, and the proceeded to get the correct answer would I get full marks for both parts? Also in q14 a ii if I forgot to cancel the g's in ydot expression and didn't get the proper answer of pi/6 would I lose a...

Can someone pm me the paper?

Hey does anyone have any idea what the aligned raw marks are for 2012 4u? On rawmarks.info there was only one entry (85->96) and I was wondering what other marks such as 75-80 would align to? Thanks :awesome:

Idk what kind of medicine you want to do but I've heard physics is pretty important in it.

Nah I want to do physics or engineering.

Calculus is easy, you'll smash it :)

80 minutes for me I think.

It's not so much the calculation part it's more so the way that the discussion is written. I have to make sure that I'm not missing out on any points such as improvements to be made to the experiment.

Well in that case do you have any tips for maximizing marks particularly in the discussion section? It is Snell's law yes.

I plan to do it yeah.

Has anyone done a prac experiment in physics to find the refractive index of a medium? If so any tips on maximizing marks would be helpful :)

It's the 2nd topic for me. First one was a local Ecosystem.

Have you guys had your half yearlies yet? I have

My school hasn't covered that yet no

Thanks liamlolz. I thought calculus was in the preliminary course (the derivative)?

Hey flying, Thanks for welcoming me :)

I hope to do physics or engineering at uni

Thanks :)
