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.
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...
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:
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.
