一、(xβ)′=βxβ-1底变指常好求导,右耳脱落往前靠;生命旺盛无与比,长出新耳变小了.说明:第一句中的“底变指常”指的是幂函数;第四句中的“新耳变小”指的原指数β变小为(β-1).二、(lnx)′=1x,(ex)′=ex自然对数易求导,颠倒真数符号消;自然指数性刚烈;任你求导不动摇.说明:
I. (xβ)’=βxβ-1 Baseline refers to the constant derivation, the right ear falls off and leans forward; the life is unparalleled, and the new ear grows smaller. Explanation: In the first sentence, “Bottom change refers to ”Normal“ refers to the power function; in the fourth sentence, ”the new ear becomes smaller" refers to the original index β becomes smaller (β-1). Second, (lnx)’ = 1x, (ex)’ = ex natural pair The number is easy to find, inverts the sign of the true number, and the exponentiality of nature is strong; if you ask for guidance, it will not be shaken.
