例句
- Every function whose derivative is linear is a quadratic function.
任意一个导数为线性函数的函数都是二次函数。 - The uncertain relationship between the double limit ond the quadratic limit is explained and the determination methods to the nonexistence of the odd function's limit are given.
摘要本文阐明二重极限与二次极限的不确定关系，给出齐次函数的极限不存在的判定方法。
