积分上限函数的具体化问题

Concretization Problems of Integral Upper Limit Function

高等数学中原函数的存在定理是重要的,但其逆定理并不成立.有些新编教材在习题中忽视了逆定理不成立这一事实,从而导致积分上限函数的具体化出现问题.要解决积分上限函数的具体化问题,必需要了解积分上限函数与原函数之间的关系.

In high mathematics function existing theorem is very important, but its contrary theorem does not hold water. Some new teaching materials neglect this fact ,therefore problems are caused when integral upper limit function is concretized.The relation between integral upper limit function and the original function shlwld be known if the concretization problem of integral upper limit function is to be resolved.
