Proof by Induction (Points)

[Twitchy]

Er...

Help por favor?

 

Gotta prove that this recursive formula...

t₁=8

t_n+1=3_tn-14

 

Has an explicit formula of...

t_n=3^n-1+7

 

 

I got the basis down, and assumed for s(k), and all that crap, I'm pretty much on the last step.

 

But I dunno how to just get the damned things to equal each other.

Really pissing me off.

 

 

If you can help with this, there's two more where that came from!

 

 

Oh, yeah, incentive.

Umm, 20 points per proof.

 

 

 

[Twitchy]

Screw you guys.

Figured it out.

There's another one, but I need it by tomorrow, and I can't check DM in school, so, yeah.

Sucks.

No points for you.

 

[ChronoCrosS]

Dang.

 

*was about to do it*

[Twitchy]

If you're curious it ends up being 3^k+7=3^k+7

[ChronoCrosS]

Ya I was gonna check on Wikipedia to refresh my memory, I did that stuff in grade 12 a lot.

[HotW Moiraine]

Wanna hear the funny thing. I've never ever seen that. And I've taken 30+ hours of mathematics.

[ChronoCrosS]

Hey! I thought you only posted pictures.  ;)

[HotW Moiraine]

Hmm, that seems familiar. And using algebra I can manipulate it to get the correct answer. Maybe your notation is just so different from mine I do not recognize what it is you are doing.

I think i vaguely recall doing recursive formulas in precalc like 2 years ago but that's all i recall with them...

I've found that taking higher levels of mathematics really starts to screw with your ability to do simpler operations.  I tend to look at everything now and think either "Derive" or "integrate"

[TheMasterDude]

I'm with Gerr on this one, I was going to help ya, (I think I remembered how to do that stuff) but I ran out of time and had to go to work by the time I saw this...

[Haxorsist]

WHY are you taking maths? It's so... impossible.

That sums up my life.

[Dunbar]

Ah yes, we just got to induction ourselves : p

[Twitchy]

Took the test today, hopefully did pretty well on it...

 

[Edielin]

Your evaluation of your performance in a test is inversely proportional to how well you -actually- did.  ;D

 

Joking, I'm sure you did well.  :)

[Twitchy]

You hurt my feelings.

I don't like you.

:(

Lulz.

[cosmicpanda]

idiots. You should all study music.

 

Come back when you can explain what a cadence is. Then you will be ready to face the world. :D

[Dunbar]

Um

 

It's something musical, to be sure

Music is just applied mathematics...

 

 

 

A Cadence is a song sung usually while jogging, with a beat in sync with the pace to help with breathing.

 

For examples, see the film Full Metal Jacket

 

I don't know what I've been told

Esk-imo P***y is might-y cold

[ChronoCrosS]

Wooo, xkcd rules!

[Edielin]

Don't worry, Twitch.

*Gives cookies*

[cosmicpanda]

eclipse, darling, not the definition I was looking for.

[eclipse0]

Darling?

 

I think Pandy has a crush on me...

 

*blushes*

[ChronoCrosS]

Ahh, true love.
