【摘要】 讨论了三类函数方程的解法。一类方程是含有变上、下限积分的函数方程,第二类方程是不含积分号也不含未知函数导数的函数方程,第三类方程是不含积分号但含未知函数导数的函数方程,对于这三类函数方程,采用不同方法转化成微分方程加以解决。更多还原

【Abstract】 This paper discusses solutions of three kinds of function equations: function equations involving integral with variable upper,lower limit;function equations uninvolving integral and unknown functional derivative; function equations uninvolving integral but involving unknown functional derivative.These three kinds of function equations are all transformed to differential equations to solve.更多还原
