High scores: Friends of mathematics majors, please enter

There are five master's programs in mathematics: Fundamental Mathematics, Applied Mathematics, Computational Mathematics, Probability Theory and Mathematical Statistics, and Operations Research and Cybernetics. If you want to engage in scientific research knowledge, it is recommended to take the basic mathematics major, and the better ones in Hubei Province are Wuhan University and China Normal University, and the employment is basically a university or middle school; And if you look at it from the perspective of employment, I think it's best to choose to study probability theory and mathematical statistics or computational mathematics, good can apply for the National People's Congress or Nankai, if you choose the province, it is recommended to apply for Wuhan University or Huake, I have a master's degree in applied mathematics at Wuhan University, and it is not very good when I am employed, so it is recommended not to study applied mathematics, statistics and computing majors have a wider range of employment, and you can also enter some enterprises and institutions.

In fact, to be honest, the employment rate of college students' corresponding majors is very low at less than 30%, so there is basically nothing for employment in the major.

If you go to graduate school, the most popular thing in mathematics right now is mathematical modeling, which belongs to the application category.

Logarithms were invented to reduce the workload of extended calculations, and they include one or more multiplication, division, multiplication, and open operations. The use of logarithms can reduce the amount of computation so much that many computations can take hours and only a fraction of the associated calculations without logarithms.

The level is not high, you look at it, if it doesn't work, just wait for the master)

Numbers, why is the high number x fissure(2 3) underivable at x=0 and x (4 3) at x=0.

1, x (2 3) is not derivable at x=0.

It is not possible to find a direct derivative, but needs to be judged from the derivative definition.

lim[f(x)-f(0)] x=limx (2 3) x=limx (-1 3)=infinity.

Therefore, the code mask at x=0 is not derivable.

2. x (4 3) is derivable at x=0.

Because (x (4 3)).'4 3x (1 3) So, x (4 3) is derivable in Chiyuan state x=0, and the derivative is 0

x=0, which is the jump break.

x=+0, limit 1

x=+0, limit 1

0 is the first type of discontinuity, where the left and right limits exist and are not equal.

x 3-1=(x-1)(x 2+x+1), the numerator denominator is reduced to x-1, so x tends to 1, no.

The high score is really fierce, so many people.

Column-only formulas are not calculated.

It was originally planned to complete the production of Ren Ju Zhao Xun guessed that it would take x days to do the work.
