对不起,原题贴错了,怪不得这么多高手进来了。原题应该是 Y* H( G7 C/ U7 s0 C
d [(a+bx)c ] /dx = -kc +s# T. ?% Q7 }& n& Z1 H$ h
where: only x and c are unknown, others are all known, requiire c = function of x, what is this function? + Z( C# X) i9 O% V \这道题难倒了我们全班的人,请赐教! " z. J0 `+ O& ]' p/ D多谢!7 H9 g. P0 e" }8 M; b# K. A
1 v: H+ u& s7 t8 O) I, C) z
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! : Y4 W& n- L" F5 P6 C' j- B( R2 A * }/ |( U! V+ u7 h) |/ I# `1 @[ Last edited by 醉酒当歌 on 2005-4-4 at 11:32 AM ]
