SUMMARY
The discussion centers on representing the function cos(nπ/2) in a general form. The user suggests that cos(nπ) can be expressed as (-1)^n and seeks a similar representation for cos(nπ/2). A proposed formula is (1 + (-1)^n)/2 * (-1)^(n/2), indicating a method to derive the general form for cos(nπ/2) based on the properties of cosine and its periodicity.
