中学数学教材的微积分部分虽然没有明确提出不定式的定值问题,而在实际上处理了其中某些类型的不定式,这是不可避免的。两个重要极限就是0/0型和1~∞型的不定式,正确理解并计算一些不定式的极限,对于深入掌握极限、导数等基本概念是有益的,研究不定式通常要进行各种形式的变形,中学教材中没有列入的罗必达法则当
Although the calculus part of the middle school mathematics textbook does not explicitly address the fixed value problem of infinitives, it actually unavoidably deals with certain types of infinitives. Two important limits are the 0/0 type and 1~∞ type infinitives. Correctly understanding and calculating the limits of some infinitives is useful for gaining insights into basic concepts such as limits and derivatives. Researching infinitives usually takes various forms. The deformed, not included in the high school textbooks
