对不起,原题贴错了,怪不得这么多高手进来了。原题应该是- ]2 I# C( _3 L9 Y; O
d [(a+bx)c ] /dx = -kc +s \# D# f( I4 }* V- ]( Lwhere: only x and c are unknown, others are all known, requiire c = function of x, what is this function? 1 u. D! _3 Q" Q! {" K$ _5 _7 H7 k这道题难倒了我们全班的人,请赐教!9 E6 U% d& t0 ]+ m' w+ C- T0 }
多谢! ' K7 Q" h) A: J/ l( ~ ; k3 { c, m! I: o5 r ]; @# f+ \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!8 U7 K8 G5 w v, U% }
