Agreed. I prefer lower case omega (the curly w to which you refer) more than upper case as well.

What modules are you actually sitting this summer?

It's so cool that you're starting Cambridge this September. Will you appear on TSR after that new chapter in your life begins DJ?

No he will vanish into thin air :lol:

C3/4, M2, Electrons, Waves and Photons, some chem exam, and STEP I

I'm actually really surprised people like nuodai and Farhan.Hanif had time to moderate TSR whilst doing a Cambridge Maths degree. :redface:

I wouldn't be surprised. He is a demigod after all!

Maybe it isn't all that demanding after all.

I ****ing execrate all of you :colone:

Whether it's a tex issue or not it appears an α2\alpha^2 has crept in just after you stated what α\alpha was :lol:
The 1t\frac{1}{t} was a clever step :smile:

Damn yeah, tex :teehee: I'm surprised you bothered to check it :rofl: Yeah, the t−1t^{-1} substitution is what cracks integrals like this :biggrin:

I like to call this type of proof...proof by intimidation :colone:

I gave it a brief glance - tbh it just jumped out at me.
I've not seen one like that :s-smilie:
I did a STEP q with ∫dxx2+2bx+c\displaystyle\int \dfrac{dx}{\sqrt{x^2+2bx+c}}
and another with a 1u\dfrac{1}{u} substitution, but that is cheeky. :giggle:

I think I remember that! Not sure which paper though, but it's a useful sub :teehee: I wonder if there's some place which just has a list of useful integral substitutions :lol:

I would love to see that list :biggrin:
61-C2
63-C1
58-S1
Any chance of an A?

Make one. :tongue:
A brief internet search shows up a few - mainly trig ones though :cool:

I'd have thought that would be a low A, rather than a high B - depends on the year and exam board of course :s-smilie:
EDIT: As MathsNerd says that is raw score right?

Is that marks or UMS? I'm not quite sure that could be high enough but you'll just have to wait and see what the grade boundaries come out as :smile:

lmao seems like something you'd do, this means I can casually make:
a2+b−c37=\sqrt{a^2+b-\frac{c^3}{7}}= ♥ or RandomMathsShiz=Random Maths Shiz= ☺
I will do so if required when joostan gives me that problem


For hidden quadratics a friend of mine insisted on using the union jack :lol:
Haha - as if I'd give you such an easy problem :laugh:

This is raw marks nor percentage or ums :smile:

Fixed the quote. :wink: I don't see any reason why not, although it may well be less than currently. Either way, I have to get there first!

Just about an A, but judging on these papers for this exam session (if this is edexcel) I'm afraid to say that seems like a very high B grade

You need 240/300 ums for an A overall at AS level maths

I predict that C1 will be 63/75 for an A
I predict that C2 will be 62/75 for an A
I predict that S1 will be 61/75 for an A

Each unit is given a ums mark out of 100
