Описание: 不定积分双元法介绍以及公式证明 双元法由知乎大佬虚调子发明,对于考研的朋友是一大福音,对于很多的不定积分秒出答案。希望双元法以后编入高等数学课本。我认为有必要向全世界推广。 Integration by bivariate substitution method introduction The dual-variable method, invented by Zhihu user "Xu Diaozi," is a great boon for postgraduate entrance exam candidates, providing instant solutions to many indefinite integrals. I hope it will be included in advanced mathematics textbooks in the future. I believe it's necessary to promote it worldwide.
