[calculus 2] Can someone explain or link a well structured explanation to chapter 10.1 of Thomas calculus textbook? I don't understand this part
I find myself completely unable to understand what this specific part is about because I'm just not smart enough, I literally cannot decode what they are trying to convey with this diagram and very minimal explanation due to the limits of my intelligence. I understand everything above this part and have no read anything past this part, I don't plan to until I understand this. I've watched the video lecture for this but the lecture was even more confusing because it wasn't very well structured. Does anyone have resources for this very specific thing? I need to understand it before tuesday.
