对不起,原题贴错了,怪不得这么多高手进来了。原题应该是! }- s$ V5 Z: `7 b4 Y1 ^

where: only x and c are unknown, others are all known, requiire c = function of x, what is this function?1 _: U9 _1 i' Y9 f: K
这道题难倒了我们全班的人,请赐教! |4 Y: C6 U3 F9 R1 Y' N
多谢! : C# T( L% [+ z( _3 E- L2 v3 A8 J+ ~) K/ A' Y$ A/ o
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!2 R+ n0 s2 Y* J$ ]8 j
