Hey guys,
I was wondering if someone could demystify and distinguish these courses for me:
Firstly;
MATH1131 Mathematics 1A
or
MATH1141 Higher Mathematics 1A
Secondly;
PHYS1131 Higher Physics 1A
or
PHYS1121 Physics 1A
or
PHYS1111 Fundamentals of Physics
I mean, How...
Hey guys, during my cram session I cam across this question. I know it's easy, but I have a mental block. Could someone kindly prove it?
x<sup>n</sup> + y<sup>n</sup> = z<sup>n</sup>
Prove that this equation has a non zero integer solution for n greater than 2.
Thanks. There may be a...
I feel sick. I'm having so much trouble with simple questions like this.
In the solutions they appear to be using the product rule. Why ?
I thought the solution to this was: 1/[1+(x/x+1)<sup>2</sup>] + 1/[1+(1/2x+1)<sup>2</sup>] (unsimplified)
I don't get it...
i) How the **** does 'h' come into it ?
ii) How is R<sup>2</sup>-r<sup>2</sup>=b<sup>2</sup> ? I can integrate it after that, so no need to integrate it for me.
Thanks in advance
I don't know how to approach these questions. Is there any theory behind it or just logic?
All I know is that the answer involves a 3^5 somewhere. Can anyone help me fill in the gaps ?
I know I need to use Integration by Parts, but I can't seem to get this out. I feel bad about this because it's only Q2 :S
I've let u'=x & v=(1-x)^n - correct so far ?
I end up with this:
I_n = n/2 Int[x^2(1-x)^n-1] .dx -yes? no ?
I don't know where to take it from there. Is...
2005 CSSA: Question 1 (b) (ii)
I got this during the exam, but looking back at it now I have no idea how to approach it. When I look at the solutions I cann follow all the steps, yet cannot understand WHY they are doing them. Could someone help? Thanks.
Hey guys,
Does anybody have the solutions to the 4u 2005 CSSA? If you could give us a link that would be MUCH appreciated.
Perhaps you misunderstood. What I mean is: does anybody have A set of solutions for the 2005 CSSA ?
Thanks.
Go ahead - estimate your RAW mark.
Please be relatively honest and perhaps even account for mistakes.
I'm doing this so that we all get an idea of where we stand. I will go first.
