Review of double integrals and the median value theorem
Learning Content:
Violent English: Take Lincoln's speech, memorize the core words of the postgraduate entrance examination that have not been scored five or six times before, and take the test.
Advanced Mathematics: Continuing with yesterday’s unfinished error correction task, it is actually about the calculation of multivariate differentials. The main problem is that the result is either missing a negative sign or the coefficient is wrong. Analyze wrong questions and record wrong questions.
Then, I reworked the questions that couldn't be done before the median value theorem. Some proof questions couldn't be proved if the comprehensive point was tested. One of them was tested on the application of Rolle's theorem and the intermediate value theorem. I thought of the conditions given, but I really didn't expect to use the intermediate value theorem to construct the conditions that satisfy Rolle's theorem. Maybe, the intermediate value theorem, I don't know how to use it in combination with the conditions given in the title!
Finally, first draw the knowledge structure of the double integral by hand, and then do 15 questions of the double integral. To interval symmetry, the integrand is an odd function, and the result is zero, or use the integral linear property to separate out the odd function, etc. ②The other is a one-variable integral basis, such as x*sin2(x) directly using the interval reproduction formula,
Study time records:
Get up at 6:00
6:40~7:45 Xiaohu clocks in, wins Lincoln's speech, and reads the first two paragraphs of a six-level reading comprehension
8:00~9:45 Experiment class
10:12~12:00 Theory class
12:20~13:30Nap
2:30~4:30 class
5:00~6:00 Error correction
6:00~7:20 run + eat
7:30~10:20 Advanced Mathematics, rework a previous problem using Lagrangian to prove inequality. I have done this problem 3 times and I am still not proficient. I only know how to use Lagrangian, but I still have to pay attention to how to use it. , For example, how to construct that function, how to finally prove the inequality relationship from Lagrangian, etc., learning to transform the brain, the only way to cause changes in the structure of neurons is high-frequency stimulation.
