关于函数周期性的一个猜想的完善、推广及应用６３８２５０四川省蓬安县实验中学蒋明斌作者在１９９１年初提出如下的猜想［１］设λ为非零常数，函数ｆ（ｘ）满足其中ａ、ｂ为实常数．ｂ≠０，则ｆ（ｘ）为周期函数当且仅当ｂ＝－１且且此时周期为ｍλ．首先指出，猜想提... The consummation, popularization and application of a conjecture on the periodicity of functions 638250 Jiang Mingbin, Experimental High School, Peng’an County, Sichuan Province The author proposed the following hypothesis in early 1991. [1] Let λ be a non-zero constant, and the function f(x) satisfy a and b. Real constants. b≠0, then f(x) is a periodic function if and only if b=-1 and the period is mλ. First of all point out, guess to mention...
