对不起,原题贴错了,怪不得这么多高手进来了。原题应该是 " b. @- L3 j5 od [(a+bx)c ] /dx = -kc +s # C" z& z! m9 N/ c d% e* Uwhere: only x and c are unknown, others are all known, requiire c = function of x, what is this function? $ W* ^$ K1 U" O2 C/ c这道题难倒了我们全班的人,请赐教!" Z" W5 S9 E' B
多谢! . e. Q9 J% K' ^9 e% ^: ` V* O8 L3 C% `5 q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! 7 F6 s& k& W' O9 }- @' e7 E# S4 p) a7 f4 [
