Anyone else got information about any other unis?

Tutorials?
Hi all,
I'm supposed to be talking to the budding mathematicians from my old school on Thursday, and am struggling; I want to talk to them about how maths is taught at universities in general, but, to be honest, I don't really know in most cases. T…

Re: FP1 finding inverse of 3x3 matrix
Really? Wow. Now i'm scared to see what's on FP2 and FP3 lol.
I'm no expert on course content, but I suspect you'll find the overall content is no different, its only that Edexcel recently moved the matrix stuff to FP3, they shuffled everything into…

Re: Rearranging formula help?!? Please!!
Are you sure this is the formula you need, because it's a bit of a pain finding t from s=ut+\frac{1}{2}at^2.
Anyway, your best bet is to rewrite it as \frac{1}{2}at^2 + ut  s = 0, put in your values of a, u and s, and then solve it like you would a…

Re: Gradient of a Scalar Field
They are the same.. in the case of grad, it is a vector (not sure if it's correct to say that, as its clearly only an operator as it is, but all the same, written as a vector) that is multiplied by some scalar field F, and the result is a vector fiel…

Re: Gradient of a Scalar Field
Certainly Grad(f) is usually defined as the vector (df/dx, df/dy, df/dz).
(Those should obviously be partial derivatives btw)
However, I've also seen Grad(f) defined as the vector in the direction of greatest rate of change of f whose magnitude is …

Re: Continuity Epsilon Delta proofs
As written, this makes no sense. You have yet to specify what \delta is.
Well yeah, but you take as read surely that the delta is the standard one in the epsilon delta proof, ie xx0<delta. Admittedly better to say that but it doesn't ruin th…

Re: Continuity Epsilon Delta proofs
Seems fine to me, don't see any problem with it, though of course you could just use that quotients of continuous functions with nonzero denominator are continuous (presuming you're allowed to quote that)

Re: COMP4  What have you done?
The number of pages you have done does not determine the grade. With carefully selected test runs, sample screen designs, etc it is possible to produce a grade A project that is well under 200 pages long  depending on the complexity of code and the…

no I mean I chose random x and y values to get a z value, for example, and that gave me a point on the plane. When I used them to find the perpendicular distance from a point to the normal it worked every time, I'm not sure why but ye.

errr wouldn't A' be A prime, rather than not A (which would be A), or maybe you're using different notation
Well I prefer A bar, but A prime is pretty well accepted, and its obvious what's meant anyway. Technically best notation is A superscript c, …
