二 the profit of buying a units of stock and b units of bond can be described
by a function W(a,b)=2^(1/2).exp{-b}.cos(a) (請原諒我不會用BBS打數學符號)
A profit-driven individual with a units of stock and b units of bond will
move in the direction of maximum profit increase.Find the equation b=f(a)
for the path of a profit seeking individual starting with a=pi/4 and b=0
請問這一題是什麼意思啊???
為了追求最大利潤，求用a來表示的b??
是這樣的意思嗎???好像怪怪的
感謝!!
