Writing a sequence in terms of n.
1. The problem statement, all variables and given/known data
given: Vn+1=Vn*cos(pi/2^(n+2)) 2. Relevant equations Write a sequence Vn in terms of n 3. The attempt at a solution we substitute n with n1 and we get: V(n1)+1= Vn1*cos(pi/2^(n1+2)) Vn=Vn1*cos(pi/2^(n+1) Is this correct?

Alright it was an extra credit question in class just wanted to make sure if it was correct. Thank you very much.

Re: Writing a sequence in terms of n.
Off topic question, do u know any good latex software i can't used the stuff given in the forums.

Re: Writing a sequence in terms of n.
I mostly use the LaTeX from the Forums.
To check my code I sometimes use mimeTeX online. Do a search in these Forums. 
Re: Writing a sequence in terms of n.
Alright really appreciate it.

Re: Writing a sequence in terms of n.
Google Lyx and/or Miktex.

Yea i can't get it to come out like that how can i do it?

Re: Writing a sequence in terms of n.
You have to enclose tex expressions with tex or itex tags. They are like the $$ or $ tags in regular tex. Right click on the expression to see the source.
[Edit] Woops, that doesn't show the tags. Start to reply with a quote to the post with the tex and you will see the tex tags. It's like this: [tox]Put your tex here[/tox] and use tex instead of tox. (If I use tex you won't see the tags).

[tex]U_{n+1}=V_{n}+U_{n}[/tex]
alright i got it to work thanx a million! 
Re: Writing a sequence in terms of n.
Yep. You can use itex for inline and you can preview your posts before you submit them to see it's all OK.
