设函数在处可导，且则[imgwidth="36"height="21"src="...b70f05bba3de85.png"]
举一反三
- 设在有连续导数，且，令，则必有[imgwidth="36"height="21"...b467225fbffaf9.png"]
- 设函数在的某邻域内连续，且满足，则[imgwidth="36"height="2...581ed8ed9dfcaf.png"]
- 设，且，则与[imgwidth="73"height="24"src="http...73413b9f76aa6e.png"]
- 设在点的某邻域连续，且，则[imgwidth="36"height="21"sr...60862d38616763.png"]
- 函数在点处可微，，当时必有[imgwidth="61"height="21"sr...5bea932add1771.png"]
