The discussion revolves around a differential equation problem involving a power series defined by the function f(x) = ∑ (9^n / (4n)) x^(2n) for n=1 to ∞. Participants are tasked with using the Ratio Test to find the radius of convergence and determining the first three non-zero terms of the derivative of the power series.
The discussion is ongoing, with some participants providing feedback on the posting format and rules of engagement. There is a mix of encouragement and critique regarding the attempts made by the original poster, indicating a need for clearer engagement with the problem.
Participants note the importance of adhering to forum rules regarding the presentation of homework questions and the requirement to show attempts at solutions for assistance.
3. Attempt at a solution.
There's still no attempt at a solution...Mivg said:I got part a no problem, but having trouble with part b.
Homework Help:
On posting questions: Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in the appropriate forum in our Homework & Coursework Questions area. This should be done whether or not the problem is part of one's coursework. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work. NOTE: You MUST show that you have attempted to answer your question in order to receive help. You MUST make use of the homework template, which automatically appears when a new topic is created in the homework help forums. [/color]
