High School Mathematics Compulsory 3 Important Formulas, What are the Formulas for High School Mathe

There are three chapters in the compulsory three courses of high school mathematics, including statistics, preliminary algorithms, and probability. Most of them are written memorization, and there are few formulas.

1.Statistics. Probability = sample size Population capacity.

Number of stratified sampling = number of layers i, total number of samples, sample capacity.

Sampling distance = population size Number of samples drawn.

Mean x = (x1 + x2 + x3 + .xn)/n

Variance s 2=[(x1-x) 2 +(x2-x) 2+......xn-x)^2]/n

Standard deviation = root number (s2).

The linear regression equation y=bx+a

2.The algorithm is preliminary.

This part of the formula mainly includes algorithm block diagram and algorithm statement (divided into sequential structure, selection structure and loop structure).

3.Probability. The probability calculation formula for classical generalizations is: p(a) = the number of basic events included in a Total number of basic events.

The probability formula for geometric generalizations: p(a) = length of the region constituting the event a (area, volume) and length of the region constituting the total event (area, volume).

Mutually exclusive event p(a1+a2) = p(a1)+ p(a2).

Opposing event p(a) = 1-p(a) pulling

Summary of the 3 formulas of the compulsory mathematics course in the first year of high school.

Young people, be pragmatic.

Don't wait, I don't think anyone will be so sassy to help you collect it.

I don't know what you're going to do.

The textbook you use should highlight all the formulas.

Visual Basic is the evolution of Basic, and there's a lot of talk about that online. In fact, I watched VB on my own in the second year of junior high school, and now I have only finished the compulsory three in math class, so I am much ahead because VB has a lot of similarities with Basic. In fact, the textbook has been very simplified, there are 5 ways to write loop sentences (including when type and until type), the textbook is afraid that you will be confused, so I specially selected two kinds of writing that are very different.

First of all, I have to be grateful that the textbook did not choose a line number.

As for the concepts, all I can say is that they are really abstract for beginners. This should be accumulated, and at the same time, it must be realized, which is the basis of programming! It's more efficient for you to figure out what these are than to write a program when you don't know.

My introductory tutorial is Visual Basic from Beginner to Advanced, from Phase One Technologies. You have to take a good look at these, they talk about very basic things. And its preface has had a big influence on me and almost determines my current programming style.

Since Basic is a product of the DOS era, and VB is compatible with Windows, the design concepts are very different (such as process-oriented [Basic] and object-oriented [VB], sequential execution [Basic] and event-driven [VB]), and the actual application should not be confused.

And ......Programming is not about "playing", but about "fun learning". If you're just using programming software as a plaything, you're definitely not going to learn how to code.

In addition to Visal Basic, what other languages can be used to run the various algorithm programs in the high school mathematics compulsory course (3) on a computer?

We know that by now, there have been nearly a hundred high-level languages used for computer software development, but the uses of various languages are different. Like what.

1. C (including C++, VC, etc.) is a language developed and used for database operation by computer operating system, and the operation of memory is one of its biggest features;

2. Fortran is a language specially used for mathematical processing, and its unique differences can be seen in array processing, output format, mathematical model establishment, etc.;

3. Basic (including Qbasic, VB, etc.) is a simple and easy-to-learn high-level language, which is the first thing beginners need to learn. In general, students can cope with simple mathematical calculations, etc., and for students, mastering the language is sufficient.
