1.(10%) I let L be the line x-4y=8. Find the equations of the lines L1 and L2 and that (i) (2,1)屬於L1 and L1平行L (ii) (2,1)屬於L2 and L2垂直L 2.(20%) differentiate the following functions (i) h(x)=g(x)^f(x) (ii) f(x)=2^√x^2-1￣ 3.(20%) optimization problems (i) find the numbers whose sum is 20 and whose product is maximal (ii) a rectangle has a perimeter L. What should the dimensions of the rectangle be if the area is to be a maximum? 4.(20%) use the l'Hopital's rule to find the following limits (i) l i m 2^x-8／3^x-27 x→ 3 (ii) l i m (1+3/x)^x x→∞ 5.(20%) sketch the graph of the following functions (i) f(x)=x^4-4x^3 on [-2.5] (ii) g(x)=2/3x^3-2x^2-6x+2 on [-2,5] 已經盡量打得好懂一點了= = -- 上帝：你到了世上要當什麼樣的人：好人︿(￣︶￣)︿上帝：這輩子還沒聽過這種要求的( ′▽`)-o█ http://www.wretch.cc/blog/waltervic 批兔:must_be -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 140.119.206.10
