請大大們算詳解給我看,感恩 Find intervals where the function f(x)=x/e-lnx is increasing or decreasing , and where it is concave upward or downward. Find also the local extrema and the points of inflection. Determine which is larger:啪/e or ln啪? 不好意思不會打特殊符號... Find the area of the region enclosed by the graphs of x+y=2 and x=y^2 using two ways (1) integration with respect to x and (2) integration with respect to y (please sketch the curves of two function and indicate the closed region) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.224.125.233
