Mathematics Corner :)

Exactly my point, a drop of infinite desity and zero radius can actually do the trick, (0*infinity=finite value), its a theoritical function, used in the sense of approximating such cases.
 
Right, that makes sense...this gets over the problematic idea of finding something expanding from nothing...

0*infinity=finite value

That's probably to be expected, like with the limits of infinite integrals and stuff, but I find it pretty cool, lol...so starting with zero volume and infinite density would still give a finite mass of oil, in a sense...essentially, though, this does mean we're allowed to approximate the initial radius of the drop as zero, doesn't it?

True, but in the end its all relative. But again the density of oil is not infinite.:D
 
You know the Christian Mattiyathu he is excellent at math. And is studying to become a math teacher inshAllah.

Lol, true...I felt how wrong that sounded as I typed it...

Ahhh well, it's an A-level question...the model's over-simplified, and even the question doesn't claim that this is the actual behaviour of the oil drop - it's just what "one observer believes" to be a good model, lol...
 
Br. GreyKode is an engineer... I am sure he'll survive without our savior!
can we get back to Math pls?.. I have been following the thread a while, let's not meander it on the laurelses of our guests..

Does anyone know those 2 triangles that you use to work out the values of trigonometric angles ?? Need ASAP; exam tomorrow :X

Edit: actually think I've got it.

Triangle 1

Angles 45
Hypotenuse: root 2
Adjacent: 1
Opposite: 1

Triangle 2

Angle: 30
Hypotenuse: 2
Adjacent: root 3
Opposite: 1

I think that's right ?:S

^The triangles to find out the values of sin 45 or whatever? It's easier to memorise them. Or that's how we've been taught.

This looks fine but you should mention that the triangles are right-angled ones otherwise it is not necessarily correct.

so how did it go, mathematcians ? those who did OCR C4 ???
Click to expand...

Do you mean OCR MEI ?

Because I'm pretty sure OCR C4 is on Friday (5th June)! *checks exam timetable 10 times* Either that or I've missed my exam...

It was OCR Core 3 today... maybe your getting mixed up with that?

^ lol dn't worry you didn't miss your exam :p

Yh I should've clarified: OCR Maths (MEI) - C4 :D
 
Is it really necessary to bring this topic up... There's only 4 weeks until school, and I was hoping to stay clear from any form of Mathematics especially. I mean, don't you guys know the secret?

Mathematics = Maths = M.A.T.H.S.

Mentally Affected Teachers Harassing Students

It's a joke. If there are any Math teachers here on this forum, please do not take offense. :skeleton:
 
I just realized I have to do Logic&Geometry and Statistics next year in uni.. Geometry I don't mind so much, but statistics..... I thought all math was over and done with...imsad

Good luck on all your exams, people, may Allah make them easy for you!
