摘要
基本初等函数:常值函数y=c,幂函数y=xa,对数函数y=log-_ax(0<a≠1),指数函数y=a^x(0<a≠1),三角函数y=sinx、y=cosx、y=tanx、y=cotx,反三角函数y=arcsinx、y=arccosx、y=arctanx、y=arccotx具有一致连续性.
The concept of uniformly continuous function, some sufficient conditions and necessary conditions are introduced. Sequentially, the uniform continuity of basic elementary functions is discussed.
