not for offending anyone but this way of teaching makes students sleep or struggle to keep up copying the boards. Change rythm, ask questions to your students, emphasize some parts. This has been a constant stream of words thou clear and linear. It's no different than reading the textbook - that's exactly what I did for many classes I had in my engineering studies as it was much more effective and time and energy saving for me studying my textbooks at home than wasting hours for going to my universities, listening to hypnotic lessons not memorizing or understanding half of what I could alone at home.... except for a very few where the professors were very good at merging notions from different texts and had the capability of making things clearer or more interesting - like my professor of linear dynamic systems - or you simply couldn't pass the exams if you didn't pick notes at lessons because they didn't follow a specific textbook.

Is there a mistake at minute 30:15 in the video? It seems there is an error in the transcription of the limits of integration. It incorrectly uses a1 and a2 as the limits for x, which should actually be a1 and b1 for the correct lower and upper limits, respectively. Similarly, for y, the limits should be a2 and b2 instead of the b1 and a2 that are shown. Could you please clarify?

@jeffryborror4883

2 ай бұрын

You are correct that her specification of the rectangular domain is inconsistent with the limits on the integrals. Rather than changing the integrals, it would be clearer to write the domain as [a1,a2] x [b1,b2]

The fundamental thing is to know how to use these formulas with multiple variables and if it is possible to improve the operation in less time and less step if in the case of the lack of data the achievement of the result is variable depending on the conditions

@amritlohia8240

Because if you work through the definition of a double integral with f(x,y) = 1, you'll see that it just sums up the areas of all the infinitesimally-small rectangles covering the region without multiplying them by anything (since multiplying by 1 leaves a number unchanged), and so it calculates the total area of the region.

Thank you.
