可微的幂指函数求导要用对数求导法则。

可微函数的反函数一定可微，其导数与其反函数的导数互为倒数。

多元函数连续必可微。

若定义域是闭区域，则连续的多元函数在其上具有最大值和最小值。

Every deliberate act of wrongdoing by the master or any of the crew against the ship or cargo，without the authorization or privity of the Shipowner or his agent，is（）.

（）, or drum is used for hauling in or letting out the wires or ropes which will fasten the ship to the shore.

A salvor may be（）the whole or part of the payment due under Salvage Convention to the extent that the salvage operations have become necessary or more difficult because of fault or neglect on his part or if the salvor has been guilty of fraud or other dishonest conduct.

逻辑运算符（AND、NOT、OR）的运算顺序是AND→OR→NOT。

设g（x）是可微函数y＝f（x）的反函数，且f（1）＝0，，则的值为（　　）。

二阶可微函数若是凸的，则（）。

可积函数一定可微。
