Re: Maths and Physics

Ah cool, for Nat Sci then, I would recommend Churchill College at Cambridge as it's really nice and it's science-oriented too as Winston Churchill granted it's charter specifically for that purpose. You should definitely go and visit it! Best of luck :P

Re: Maths and Physics

Damn, is there no way you can do the full A2 in FMaths? Because there are lots of really cool stuff like Taylor Polynomials and stuff that aren't introduced until the second year. Anyway, it's definitely worth studying FMaths, it can be pretty hard, but see if you can get your school to get you a us...

Why aren't these two integrals the same?

Right, we all know the classic problem. \int e^x cos(x) dx = \frac{1}{2} e^x(cos(x) + sin(x)) But according to the Wolfram integrator, \int \frac{e^x}{\sqrt{tan^2(x) + 1}} dx = \frac{e^x (tan(x) + 1)}{2\sqrt{sec^2(x)}} But shouldn't the...
