MATHEMATICS, anyone wanna try?

[Chareos Rantras 0]

I'm stuck on this fella right here.

If anyone knows would be nice! (hopefully I'll find it myself soon, still I wanna kno your answers). I know it's in Dutch but try to look at the numbers & letters ^^

 

 

 

 

Thx in advance!

 

cheers!

lol found it with a friend's help, I needed to take a double value at the discriminant like this:

 

p² + 2p + 1 => D = 0

so equals to (p +1) * (p + 1)

 

 

OR just change p² + 2p + 1 = ( p + 1 ) ² like below:

 

 

 

Now it's back to teh study table!

 

cheers!

lol...the maths makes sense, but the dutch loses me...what were you trying to do? Prove two series are equivalent?

Nope.

EDIT: Oh... I get the Dutch, it is the math where I get lost

Yea I had to prove that the first formula is equivalent (Left side equal to right side of the formula). And the subject of this paragraphe is 'proof by induction' so I needed to use the induction method.

 

 

@Timo, Barri & Gogo: Yea that was my first reaction too when I saw my 300+ pages course book (agreed, the book isn't that big, but the math let's it seem like 1000+ pages)

 

 

cheers!

I do love a good puzzle but I'm much more curious about the secret messages. Makes yah think twice about how you scan eh, lol.

Hahahaha ! Nice one Brad !

OMG! ITS TEH TREASURE MAP! to the cookie vault of D.a.r.k no doubt about it!

Umm that's not mathematics....math is like 1+1 and 5 x 10.....it does seem a lot like what I'm seeing on the signposts throughout Ancaria though

300+ pages is nothing...mine was 2000 pages but I was cheap and found one that only had the second half to save cash...ergo half the size. Too much maths in any case.

With 2 kids and working full time I'm lucky to remember my own name lately *rofl*

My daughter found this math thread and asked me what the proof would be, I thought it was for her school and so I helped her with an easy 2 minute proof, using a telescope sum.

+1	 1	 1	 1	2-1   3-2   4-3   5-4   1   1   1   1   1   1   1   1	   1	 4
--- + --- + --- + --- = --- + --- + --- + --- = - - - + - - - + - - - + - - - = 1 - -   = -
1*2   2*3   3*4   4*5   1*2   2*3   3*4   4*5   1   2   2   3   3   4   4   5	   5	 5

The inner sums have pairwise opposite sign. So only the first and the last term remain. Which would be 1-1/(n+1) = n/(n+1).

At least she learned about telescope sums, because I thought she wouldn't understand a proof with induction at her age. And then I had to explain her induction. So obviously no sacred playing today.

 

I paid university, first kid and room with correcting math homeworks. This type of maths is like sports, you need training to see an easy solution. And 4 years correcting this stuff is a lot of training.

Haha, agreed Chattius.

 

I thought you had just needed to simplify the problem, Rantros, not rework it, so I probably would've messed it up. The Dutch confused me XD;;;;

[claudius 104]

Whoa I'm glad I found the right thing for me in school. This looks hard. I did take some calculus but I did not do any proofs it was like applied math as applied to solving engineering problems or in my case chemistry..

[Arperum 3]

The math in here is relatively easy to some of the stuff I had to do when I was studying Math at the university(gave up because to many physics for my liking)

[Furian67 15]

Put a wrench in my hand ok, solve math problems like this or even chattius's ? Too Much eeeeeeeeeee

[Bondbug 32]

OMG! It's 65 years since I last saw stuff like that. Go away Chareos, you make me feel old (older, senile, wizened, decimated, scrapped, there's a good word somewhere that I cann't quite put my finger on, etc).

 

Thanks heaven the problem was solved before I got here. Better get the oil can out and ease a few of the rusty bits if we are going to have much of this stuff on the forum.

LOL. Bondbug, I love that your part of our community! As Chareos would say, you get two cookies.

[Bondbug 32]

Sounds good; I will try them when I get my teeth back.

 

At present, mathematically speaking, it is something of a geometric impossibility.
