对不起,原题贴错了,怪不得这么多高手进来了。原题应该是! g. N( [( u5 _: g: I) z
d [(a+bx)c ] /dx = -kc +s) F. Q; |+ s$ f
where: only x and c are unknown, others are all known, requiire c = function of x, what is this function?9 h: J% r! y, c+ n
这道题难倒了我们全班的人,请赐教! , W5 p2 _$ H) E( W3 k多谢! X. ?) L; J/ y- @4 _ / ]" e1 V4 e- }2 R% @: `1 ]7 E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!$ f+ ?9 t5 y7 Z
