对不起,原题贴错了,怪不得这么多高手进来了。原题应该是" q9 V0 v. g# c2 q7 t
d [(a+bx)c ] /dx = -kc +s ) [8 K4 l) I. z5 k$ n+ xwhere: only x and c are unknown, others are all known, requiire c = function of x, what is this function?2 N' B* W% @ @( ?' H* L1 }
这道题难倒了我们全班的人,请赐教!7 ]/ \! v/ d% O4 E" j
多谢! Y# m1 |2 x' V4 N7 }4 P* ?
& p/ x" n1 h; l4 ]' T; \; g' Q要求用x的函数来表达c.也就是等式右边不能包含c. 即 c = x 的函数, 所求就是这个函数。多谢!" t4 Q: ~# Y! ^* y1 l
