[sbsash]

This thread is to challenge each other with math problems.First someone asks a math question then everyone else tries to guess/find the right answer.After that question is answered,someone else asks a question and so on.I'll start it off.

Q #1

Find the values for x,y,and z,so that all of the following statements are true.

*y > x , z < y, and x < 0

*z /(divided by) 2 and Z / 3 are integers

*x / z = -z (negative Z incase u missed the sign)

*x / y = z


Took me about 5 mins to find the answer.

You mean to propel each other to do your homework?

Then tell us the answer to prove it.

aaarrrggghhh...the first one is ruined.

y=10, x= -5 (negative 5), z= -2 (negative 2)

The second condition that z / 3 and z / 2 both are integers are not fulfilled in this solution.

i agree with you and rommel.. comeon, smth more interesting .. science or geography would have been cooler.. for gods sake not maths

trust..then wen being millionares then thell be jealous

still

Now someone else come up with a question.Oh,and please don't ask a question that you don't know from your homework.

[Zunaid]

Can one demonstrate whether NP-problems are actually P-problems?

While you are at it, prove that every number > 2 is the sum of three primes. My friend Goldbach considers 1 to be prime.

I was about to write the proof, but I don't think the space here is enough notwithstanding it may be constituted as spam.

[Antora]

OMG seriosuly....why is there a thread on maths? I agree with Rommel, NERDS =P bahah

[Zeeshan]

Sigh! Do I really have to resuscitate another dying thread?

Here you go: math picup lines courtesy of boss:

Top Ten Math Major Pick-Up Lines

10. You fascinate me more than the Fundamental Theorem of Calculus.
9. Since distance equals velocity times time, let's let velocity or time approach infinity, because I want to go all the way with you.
8. My love for you is like a concave up function because it is always increasing.
7. Let's convert our potential energy to kinetic energy.
6. Wanna come back to my room....and see my 733mhz Pentium?
5. You and I would add up better than a Riemann sum.
4. Your body has the nicest arc length I've ever seen.
3. I wish I was your derivative because then I would be tangent to your curves.
2. I hope you know set theory because I want to intersect you and union you.

^ Funny and interesting.

Where is the next Mathemetical Problem?

[Purbasha T]

Ok, I got one.

(X-a) x (X-b) x (X-c) x........x (X-y) x (X-z) = ?
[Clue: You don't need to do serious multiplication to find out the answer, there's a trick in here]

Btw, the capital X's refer to the variable; and small x's refer to the multiplication sign.

[Imteaz]

It is 0.

Because (X-a) x ............ x (X-X)........... x (X-z)

Anything multiplication with 0 = 0

Next Please.

....

Your answer was

aaarrrggghhh...the first one is ruined.

y=10, x= -5 (negative 5), z= -2 (negative 2)

When does (-2)/3 = integers? Am I missing something here? integers have different meaning than whole numbers?

[Tigers_eye]

Not only that:

*x / z = -z (negative Z incase u missed the sign)

Your answer was

aaarrrggghhh...the first one is ruined.

y=10, x= -5 (negative 5), z= -2 (negative 2)

???
(-5) / (-2) = +2. ???

*x / y = z.

z=-6
x=-36
y=6.

sorry.Made a mistake in my math.Learned the real answer today at school.Anyways,I'm only learning pre-algebra. I will learn algebra next year inshallah if I manage to stay in advanced math.

here is a tip that my Grand father taught me. "After finishing a problem make sure you do a revision." He was a gold medalist from Aligor before partition.

For Trignometry here is another thing he taught me. Based upon that only I passed Matric and Inter.

"lombo korno bhumi korno sin cosine'er maan
lombo bhumi bhumi lombo tan cotan'a janan."

The entire trignomatry is based on this sholok.

I used an entirely different "sholok" to make me remember trig identities. It's:

O/h!!
A/hh!!

Now that your dirty minds are over this, here is the revelation. The screams refer to opposite over hypotenuse and adjacent over hypotenuse. Bas! Once you get those two you can find tangent because it's the first part of the first one over first part of the second one: opposite over adjacent. And for the rest all you need to do is reverse them accordingly.
