对不起,原题贴错了,怪不得这么多高手进来了。原题应该是 ! v" A8 J4 K( h D& I6 U# I( T; Od [(a+bx)c ] /dx = -kc +s 7 R# ]& s( b1 `4 v( |$ R3 _: J! Swhere: only x and c are unknown, others are all known, requiire c = function of x, what is this function?* ?0 S* U1 x9 V: u/ f
这道题难倒了我们全班的人,请赐教! - a( @/ B4 I+ J, C4 C* s多谢! ; R& h: E6 z2 D3 V5 s' w A2 P0 I # j- y- `* C# f( R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!& e, I: W4 [ C- W3 m
