The discussion revolves around understanding the solution process for a double integral, specifically focusing on the steps taken to arrive at certain denominators in the integration process.
The discussion is exploring different interpretations of the integration steps, with some participants providing insights into the derivation of formulas. There is an acknowledgment of the need for understanding rather than rote memorization.
One participant notes a gap in their knowledge due to time since last studying calculus, which may affect their understanding of the current problem.
You don't need to know that formula, but you should know how to derive it. rockfreak.667 used a very simple substitution to get it.Chandasouk said:Oh, should I know that formula or do most people look that up in a table? Been a while since I did Calc 2.
