Show that the balance of P dollars invested for x years st s annual interest
rate R compounded continuously is Pe^(Rx)
大概知道题意但不知从何证起
In the method of Lagrange multipliers, f(x,y) is objective function
g(x,y)=0 is the contraint function, (x_0,y_0) is the onle solution
then lim △f
△x->0 -------| = ??
△y->0 △g |(x_0,y_0)
f(x,y)在(a,b)可微的定义..??
是f(x+h)-f(x) = y˙h + o(h)..?????? 还是这是再点X可微的定义
小弟爬过文了未找到答覆
请多赐教了感激
