Re: Find the general term!!!


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Find the general term!!!

They are all correct. The problem is they are sometime shifted.

Re: Find the general term!!!

Yes,all of those are correct. I missed the minus sign in your rec equation. Good job,bobbym!

May I ask how you derived the general formula?

Wow,you explained it to such detail! I understand it perfectly.

Joke aside,what do you mean-square root if 2?

Re: Find the general term!!!

We had this discussion in another thread. I tried to explain it then but I do not think I did. Remember the difference between a hand problem and a computer one?

Re: Find the general term!!!

There are methods to derive them but they are tedious and error prone.
The rule is whenever you learn a technique you immediately teach your computer
how to do it too. Then from that point on you get perfect answers at much higher speeds.
Those are all one line commands in M.

Re: Find the general term!!!

I got the answer by using GFs.

Could you maybe show me next weekend how to write a program for something like this in Maxima?

Your typing is getting worse. tongue

Can you write the algorithm down or post it here?

I would ask why,but it could and would turn into chatting.

Did you write down your algorithm?

Re: Find the general term!!!

No,there is only one bobbym. Otherwise the world would crumble to pieces. So you didn't write down the algorithm yet.

Hi;

No, what I did was write it for a machine whose language I no longer understand.
