I am a student of xxx class (X) majoring in mathematics and applied mathematics. Under the careful guidance of teacher xxx, I finished my graduation thesis "Existence Conditions of Integral Factor". Thank you teachers for taking the trouble to participate in my thesis defense. Next, I will report the main contents of this paper to all teachers and ask them to criticize and guide. At that time, I chose to study the existence condition of integral factor because the solution of first-order differential equation is the basis of the whole differential equation. Generally, there are two ways to deal with it: one is to convert the first-order differential equation into an integrable equation based on the equation with separable variables, and the other is to replace it with appropriate variables; In addition, on the basis of fully differential equation, the first-order differential equation is transformed into fully differential equation by using integral factor method. However, it is not easy to find the integration factor. General textbooks only introduce how to find the integral factor according to experience or observation. In this paper, I summarize and give several methods to solve the integral factor, which is helpful to deeply understand the related content of the integral factor, further study the ordinary differential equation and make the process of solving the first-order differential equation easier.
After reading a lot of relevant materials, I have a general understanding of some specific integral factors, and after discussing with the teacher, I have determined the overall thinking and research direction of the paper. In the process of writing my thesis, I mainly collect theoretical materials from online papers and periodicals, library bibliographies and learning materials. With the guidance and help of teacher Zhang Feiyu, the main reference materials are selected. After reading the main reference materials, drawing up the outline, writing the first draft of the opening report, the first draft of the graduation thesis and revising it, it was formally finalized at the end of xx, xxxx.
Specifically, my thesis can be divided into two parts: firstly, the concept of true differential equation and the necessary and sufficient conditions for the equation to be true differential equation are introduced, and then on the basis of understanding the concept of integral factor, some specific conditions for the existence of integral factor are summarized and discussed.
After writing this paper, I learned a lot of useful things and accumulated a lot of experience. However, due to my lack of ability, many content expressions are insufficient, and many problems need further thinking and exploration. I hope that all teachers will put forward valuable opinions and point out more mistakes and shortcomings, and I will accept them with an open mind, so as to further study and research and improve the paper. thank you

Three-year-old high school students have been alive. Looking back suddenly, I feel a lot. When I first entered high school, everything seemed to be full of novelty, so I was eager to try everywhere and hit a wall. However, after learning from mistakes, I learned a lot. In this high school life, I not only strive to complete my study goals, but also use various activities to enrich my life and increase my talents. Learning is the foundation of students, so I always put learning first. In the past three years, there were many classes in the school. Because of this, only by cherishing every minute of study time and resolutely not being late, leaving early and skipping classes can we have a good high school study career!
At the same time, I think high school is a period of continuous improvement and enrichment. Based on the principles and objectives of professionalism, all-round development, learning to be a man and all-round development, I took the initiative to participate in social labor practice courses, which made me make great progress in cultural knowledge, ideological quality, social practice and interpersonal communication.
Although I have made remarkable progress in all aspects in the past three years in high school, I am also soberly aware of my own shortcomings: lack of research spirit. In the future study, I believe I can overcome this shortcoming and serve my country better with what I have learned.
Generally speaking, in the past six months, the mentality of senior three students has changed significantly compared with that of senior one and senior two students. They are more active and motivated than before. It seems that they have gradually found a brand-new method, become more focused in class, improve their efficiency a lot, and feel that their mentality has been adjusted, but psychologically relaxed. I can face every day positively, take a good class every day with a more calm and mature attitude, and also take the initiative to solve problems.
I also hope that I can go further on the original basis in my grades, make up the gap between the weak subjects and others, and work harder on the weak subjects.
Still smiling at everything, ladies and gentlemen, there are still a few months left. We should not slack off. We should study with greater enthusiasm, work hard and try to have a wonderful summer. Not every day, but you should do your work in a down-to-earth manner. Peace of mind, do not forget the current' main task', can not let go of any problem, step by step into June!

Through the knowledge I learned in senior three, I took another step forward. Suddenly, I still miss it. I want to thank my teacher for imparting knowledge to me and my classmates for their concern. Let me thrive in this beautiful campus, so the first semester of senior three ended. Ushered in the long-awaited winter vacation.
Time flies and the stars run. I have been a member of my class for more than half a year. Looking back on the past six months, I have a lot of feelings in my heart. Every day I have experienced in the past six months has left a permanent mark in my heart, because these marks have witnessed the growth of such a new student. Over the past six months, I have gained a lot through continuous learning. Time is so ruthless that we go forward without looking back, but we are chasing it to avoid being left behind. Yes, no one wants to be left behind by time. And we also grow up little by little with the passage of time. And that beautiful innocence has matured with the erosion of wind and rain. Maybe this is the price of growing up. Recalling my days as a candidate seems so far away. I learned to cherish hard-won in my longing; Understand the truth that has been brewing for a long time in thinking; I didn't know the sweetness of hard work until after the harvest. Suddenly I feel like I understand a lot of things, but when I think about it carefully, I don't think so ... What I saw before was so biased and superficial, and the innocence in the past seemed to suddenly become ignorance and ridiculous. I wonder who is not like this? Maybe in the future, we will laugh at the smallness of the present ... and we will look back on the road we have traveled with a smile. ：
In study: I know the importance of study. Facing the scientific conclusion that 2 1 century, an era of knowledge, knowledge is power and science and technology are the primary productive forces, I think I will be a useless person without knowledge. The era of "capitalist" with capital as the most important productive force is about to pass, and the era of "knowledge family" characterized by knowledge is coming soon. High school is the golden age for learning modern scientific knowledge. I should seize this favorable opportunity to arm my mind with knowledge, which is priceless.
In terms of discipline, we can basically do it: respect teachers, and students can treat each other sincerely; Abide by all disciplines, public order and social morality of the school; Don't be late, don't leave early, don't skip class; Wear school uniforms at school; Civilized and polite; Have good hygiene habits and don't litter.
The above is my personal summary of some aspects at the end of last semester in senior three. I will use this summary to review the past and determine the future development goals. I am full of confidence in the future. Naturally, this requires the careful training of teachers and the sincere help of students.
