MATHEMATICS LOVER..... PLEASE

Hey guyes and Girles please Mention your Gender
So to bring

Results.

and PSYAH , please it is not questionair thread.

Re: MATHEMATICS LOVER..... PLEASE

Not really mathematics, but quantum physics was fun (and a headache).

Ech… ok, let me have a try (sorry for the crap rectangular illustration!):

Lets label the rectangle as “ABCD”,length a=AB=CD, and
width b=AD=BC,
where a>=b
centre of the rectangle is lablled as “O”
Folding A up towards C means a reflection A<->C on the crease PQ

So, the crease PQ is perpendicular (at an angle) to AC at O.

From the similarity of triangles APO and ABC, we can say that:
PO : BC = AO : AB, or PQ : AC = BC : AB.

So:
PQ = (b/a) x squareroot(a^2 + b^2) = b x sqareroot(1 + (b/a)^2)

Yeah, that’s right… i think…or i just confused myself :konfused:

S=> Small Side of the rectangle
L=> Large side of the rectangle

X=> the point at which you need to rotate the paper so that the opposite sides touch

Such an X must form a right angled triangle

Therefore from Pythogaras Theorem we get
S^2 + X^2=(L-X)^2

Simplifying this we get

X=(L^2-S^2)/2L -(i)

Now, the crease will form a right angled triangle if we draw an imaginary line
from X parallel to the side S(which will be offcourse of length S),
The small RAT on the top left & the one at the bottom are similar (it has something to do with a side & and two angle being same) which makes th base of the crease triangle of length L-2X, for our problem the crease(hypotenus of the imaginary triangle) has to be L,
So, again using Pythogaras Theorem we get

S^2+(L-2X)^2=L^2

simplifying this we get

S^2-4LX+4X^2=0 - (ii)

Substitute the Value of X from (i) in (ii)

S^4+S^2L^2-L^4=0

This equation will have 4 roots,
2 Imaginary,1 negative (which we will discard as not applicable in our case) & One

will lead
l/s=Sqrt(2)

1, 2, 5 + 3, 4, 2+4, 2, 7

So ,

It means that

Female Math Lover 5
Male Math Lovers 4

and For those who dislke (Male/Female) 1-1

Result 5-4=1

It means Girls Like Math , and this perception is wrong that girles hate math.

Re: MATHEMATICS LOVER..... PLEASE

I am proud to boast the fact that from 4th grade to 13th grade (A-level), every maths teacher (almost) have told me that I have got a huuuuuge aptitude of Maths. I just sporadically get highest marks however I never got a single B in Maths. (until last year owing to some genuine reasons.)
I guess I automatically qualify as a Maths lover. Infact..... I am MARRIED to maths.

I am a Male.

Re: MATHEMATICS LOVER… PLEASE

If that’s the case, Uneeb, then please try figuring out the maths question Psyah posted on the first page… :hehe:

i :wub: maths..

Re: MATHEMATICS LOVER..... PLEASE

i am in love wid math completely!!
