For example, there are three voices, and occasionally they are silent.
Listen to others,
At the same time, I will express what I want to say. "
-Faucoeur's Biography of Bach
? This is a very boring day and a very enjoyable time. Leaving the mobile phone, there is no contact, and the high number on the desk makes people very rogue. Complex operations, complex formulas, and that meaningless theorem. At this moment, "physical fog" has become "there are trees in the number" If you don't dig him, you will hang him after all. This seems to be an unchangeable truth.
? The fun in boredom may only be the Kindle carried in the bag every day! I wish I had a math book that I could read as a story. As a result, the hope has come true. In Math Girl, love and friendship jump among the characters; The functions are mixed with jealousy and sweet fruit, which is the mathematics in the eyes of Jiechenghao Japan. A unique youth training manual, a readable mathematics.
? "Beautiful cherry blossoms are in full bloom. . . . . . Everyone starts school in the new semester. . . . . . In this historic school building. . . . . . Study hard and exercise well. . . . . . Teenagers are eager to learn, and old people are eager to learn. . . . . . "
? In this beautiful season, in the headmaster's long speech, we look forward to tomorrow's campus life and imagine a bright future.
? The girl under the cherry tree, with a delicate face and black hair, is so delicate. It's just that she is mumbling "1 1 2 3", and she is addicted to digital games alone. I crept up to her and whispered, "Next is 5, then 8, 13,,," She lifted her face and put her finger to her mouth, "Shh". . . . . . In this way, we met by chance, under the cherry tree, in the digital kingdom, we became best friends. Mirka, a beautiful girl with beauty and wisdom. From then on, in the kingdom of mathematics, I never had a person to accompany her all the way. We write "love letters of mathematical formulas", play Fibonacci series, and waltz with W in the digital kingdom. . . . . . .
? Too many, a lovely but serious girl. Once upon a time, we talked about the past and said that we had walked through the campus of youth. In this way, we became the closest seniors and sisters. Her melancholy about mathematics, her sensibility about numbers, and her seriousness about digging into the roots make me very happy. The library and classroom are the places where we meet, and the only reason for each meeting is math. Formula derivation, inequality investigation, mystery of vibration function, infinite series interest. . . . . . Every afternoon, we are intoxicated in the kingdom of mathematics and indulge in the exploration of the father-son bond between sequence and generating function. . . . . .
Two math girls with their own styles, with a cavity of love, we talked about math and the future of numbers. This book, the first math reading outside the major, makes me satisfied.
? Once upon a time, I also loved mathematics, and the pleasure of brushing the questions always made people memorable; I also like to explore numbers, and every little gain makes me satisfied. However, the beauty of skin is superficial after all. Although advanced mathematics, calculus and Taylor formula are all memorized, they can't resist his vagaries. Here, beautiful words and warm stories turn digitalization into HongLing, touching a budding heart; Here, the irregular W (Omega) has a beautiful waltz and dances hand in hand in the library. From here on, the formula seems to be no longer boring and jumbled, and it is groped and groped with language communication again and again. From Fibonacci sequence, identity to infinite series, to differential, and finally to Taylor formula, we have mastered it step by step.
Mind maps of Taylor formula, differential, convolution, infinite series and other formula theorems are being sorted out. Mind mapping is recommended here, learning how to disperse thinking, how to take notes and remember, and understanding and remembering after trying is very effective.
? Finally, share a touching sentence: "If you always pursue what you like, you will have the ability to distinguish between true and false." . Some students like to answer questions loudly, while others like to pretend to be smart. These students must like to stick to their own opinions. They think dignity or face is very important. However, if a person has the habit of thinking with his own head and knows what is true, there is no need to stick to his own opinion. Even if you answer loudly, you won't work out the general formula. No matter what others think or say, you just need to understand what is going on. I think it is very important to pursue what I like and the truth. "
