[微積] 2題
1.The marginal cost for producing x units of a product
is modeled by dc/dx=32-0.04x . It costs 50 to product one unit.
Find the totel cost of producing 10 init?
我作法是想說一單位成本50
10單位成本就是500 把500帶入MC式子得MC=12 然後把MC積分總成本就是12x
不知道有錯嗎?
2.Find the area of the region bounded by the graph
of the equation y^2=4x^2-x^4
