    Limit Sequence
AI Thread Summary
The discussion revolves around finding the limit of the sequence defined by the sum of (1/3)^k from k=1 to n, where n represents natural numbers. Participants express confusion regarding the notation used, particularly the meaning of "(sn)n" and "n(sum)k." Clarification is sought on whether "n" is a subscript and the interpretation of the summation notation. The need for a clearer understanding of the mathematical expressions is emphasized. Overall, the thread highlights the challenges in interpreting the sequence's limit.

Sorry, I don't understand what it means either! is either of the "n"s in "(sn)n" a subscript? What does (sn)n= N mean? what does n(sum)k mean?
 

Thread 'Family of lines that are at a distance of 5 from the origin'

I picked up this problem from the Schaum's series book titled "College Mathematics" by Ayres/Schmidt. It is a solved problem in the book. But what surprised me was that the solution to this problem was given in one line without any explanation. I could, therefore, not understand how the given one-line solution was reached. The one-line solution in the book says: The equation is ##x \cos{\omega} +y \sin{\omega} - 5 = 0##, ##\omega## being the parameter. From my side, the only thing I could...
