请教大家一道微分题,多谢!(原题贴错,现纠正,多谢!) n) P1 o9 i0 C' C: \$ h$ \1 y
) J$ Z( T4 I; m, L, Q: {d [(a+bx)c ] /dx = -kc +s 1 [. [% u* s# q
where: only x and c are unknown, others are all known, requiire c = function of x, what is this function?$ H* U/ Q0 I6 {* H
对不起,原题贴错了,怪不得这么多高手进来了。原题应该是 ( B9 @# |( Y- b5 L' Z' M5 o# sd [(a+bx)c ] /dx = -kc +s1 G( z7 ]; k* l5 [5 U% |' D: m
where: only x and c are unknown, others are all known, requiire c = function of x, what is this function?+ ~* M3 G7 l& C( D- j: J
这道题难倒了我们全班的人,请赐教!& z0 Z1 H8 D: Q" o9 ]
多谢! ) f& ~" t0 {6 J# S' C" J% [ ) b: F5 ]2 ?& h# {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! 1 s; ~8 s' g6 ? o' c" F. `- @" ~8 M! t& i- \/ V
