Sequences and Series,of our counting sequence was certainly one of the greatest of all humankind. And we can use this sequence as a basis for generating even more sophisticated mathematical concepts. From the notion of a sequence we can evolve the concept of limits, one of the most elegant and beautiful ideas in all of mathematics.作者: 彎腰 時(shí)間: 2025-3-22 15:52
