Solving math problems Does he know computers?

The class leader of Class A does not understand computers.

The reasoning process is as follows:

Assuming that A is true, then B and C are false.

But A and C can exist at the same time, so they contradict the previous sentence, so the assumption is wrong, i.e., A is false.

In the same way, if C is true, then A and B are false.

But A and C can exist at the same time, so it contradicts the previous sentence, so the assumption is wrong, that is, C is false.

It can only be true from b.

Assuming that B is true, then A and C are false.

However, a and c can exist at the same time, so there is a case of the previous sentence, so the assumption is correct.

So it was concluded that everyone in Class A did not understand computers, that is, the class leader of Class A did not understand computers.

The class leader of Class A understands computers.

Since the first and second are negative, then one of them is true, then only the whole class understands computers and none of them understand computers.

If they don't understand it, then the second and third articles are true, and the conditions are not met.

Only if everyone understands computers, then the first one is true, and the others are false, then everyone understands computers.

Naturally, the squad leader also understands computers.

No, you don't. First of all, I personally think that it is necessary to be good at mathematics, but this mathematics is not the "mathematics" that we are familiar with. The computer profession that everyone generally understands is to knock symbols on the computer, which is programming.

The mathematics as we understand it is addition, subtraction, multiplication, division, or a little more advanced addition, subtraction, multiplication and division. Or maybe it's a rare proof question, those geniuses who soak in scratch paper. Mathematics in computers does not refer to trigonometric functions, analytic geometry, nor Pythagorean theorems, Lagrangian or even Maxwell's equations, but mathematical thinking.

Don't play word games anymore, and to sum up, you don't need to have good math scores, what you need is mathematical thinking ability.

Sampling frequency, this travel rate = amount of data, number of channels, time, number of quantization bits, number of bits, number of bits per byte.

80（khz）

The answer is either Suspicious or C

There is no need to dream all the time, it is better to go to work and make money quickly to realize your dreams.

First of all, mathematics is a basic science, take the computer industry as an example, because software research and development problems are mathematical problems in the final analysis, so learning mathematics well is of great significance to computers.

Of course, with the continuous development of the IT industry, the difficulty of developing soft models without parts is also decreasing, and a large number of application-level development positions do not have high requirements for mathematics, such as front-end development, mobile terminal development, web development, etc., which involve mathematics and other places that involve mathematics, so even if the mathematical foundation is relatively weak, you can also engage in software development at present. However, if you want to work in an R&D-level role, you need to have a solid foundation in mathematics.

At present, it is the era of big data and artificial intelligence, big data and artificial intelligence are typical interdisciplinary disciplines, the basic knowledge of big data includes three aspects, namely mathematics, statistics and computers, and artificial intelligence involves more basic knowledge, including philosophy, mathematics, computer, economics, neurology, comma hui linguistics, etc. Therefore, if you want to engage in the development of big data and artificial intelligence, mathematics is more important.

A computer is just a tool that helps you be more efficient; Learning mathematics is a kind of ability improvement and proof.

<> this problem is very simple, using the elementary row transformation to transform the zeros.

These computer math are actually very simple, and then you can open excel, and then the functions in 666 can be divided into them.

That is: 16 1 x and then multiply by subtract the calendar silver to calculate the fruit of the big rotten fruit multiplied by and done.

Substituting x3=9-3x2 into the algebraic formula of each x3 is obtained with x1 as the abscissa and x2 as the ordinate, and the domain is defined to obtain the optimal solution x1=0

x2=5/2

max=9-3(x1+x2)=3/2
