What's the difference between a and B

What's the difference between a and B

The main reason is that the scope and difficulty of the subjects are not the same. Advanced number one (a) must take the three subjects of advanced mathematics, linear algebra, mathematical statistics and probability theory, and its difficulty coefficient is higher. However, advanced number two (b) only focuses on one or two of the three subjects, and the difficulty is much lower than advanced number one (a), The comparison between the two is similar to the mathematics of science and Arts in the college entrance examination! I believe you should understand!

The difference between Advanced Mathematics I and B

The difficulty and capacity are different. See the syllabus or teaching materials, and compare them

On the proof of higher numbers
Let f (x) have the second derivative on (0, + ∞). We also know that for all x > 0, there are | f (x) | ≤ a, | f '' (x) | ≤ B, where a and B are constants. It is proved that | f '(x) | ≤ 2 √ ab. (. X > 0)
