It's not unusual to write a paper in engineering, so it's not unusual to check the duplicate? My brother studied engineering at that time, and most of his classmates were doing graduation projects when he graduated. The original data is different, so it is naturally unnecessary to check the copy. But two students are even worse, doing graduation thesis. I happen to be one of them. But fortunately, I don't need to check my weight. But I am also confident that the duplicate checking rate is not high, because many of my spaces are drawings.

Get down to business. There is no way to change the formula. Unless you change all the letters in the formula, and then add comments below, what each letter stands for. I want to build a mathematical model for my graduation thesis, and the meaning of letters in the formula is explained by notes.
