SUMMARY
The discussion centers on the concept of Fourier Series, specifically focusing on half-range expansions. A key point is the importance of correctly identifying the length of the interval (L), which should be π for half-range expansions. Participants clarify that using L as π ensures all basis functions are utilized, avoiding the omission of half the interval. The confusion arises from the difference between the teacher's solution, which uses "sin nx," and the student's "sin 2nx," highlighting the significance of understanding the basis functions in relation to the specified interval.
