Infinite Surd Help
Hi there, first time poster here.
I'm having trouble with infinite surds.
I understand that as approches infinity approaches zero.
I understand that the limit of the sequence is the exact value of the infinite surd.
I also know how to solve the surd by setting it equal to x and using quadratics.
But what I don't understand is how to connect any of it. I can't explain how to get from to the exact value.
In other words, I'm at point A and I know where point B is, I just don't know how to get there.
I'll simply redirect you toward the following thread: http://www.mathhelpforum.com/math-he...nite-surd.html
Hope this helps!
I appreciate the help, but I already knew about that method. What I don't understand is how I'm supposed to reach that method using only http://www.mathhelpforum.com/math-he...8b5b96b1-1.gif=0 as n approaches infinity.
The equation you're posting makes no sense: an - an = 0 ..... Please post the correct equation using appropriate notation.
