一种常见的不定积分错误

A common error of indefinite integral

高等数学中,函数不定积分的结果中有个表示任意常数的C。对常数C处理不当,是求不定积分时出错的原因。通过例子说明原函数不同时,注意常数C的不同。并且求出两个不同原函数之间相差的常数来帮助理解。

In the higher mathematics, function of indefinite integral results in a representation of arbitrary constants C. The con-stant C processing is undeserved, was the cause of error for indefinite integral time. Through the example of the original function at the same time, attention should be paid to the constant C is different. And calculate the constant phase difference between two different primary function is to help understand.
