n+1 -n
1. 0.5-0.05+0.05-0.005+...+(-1) 5 x 10 +...=
x
2.Find the area of the region bounded by the graph of equations y=e , y=x^1/2
at x=0 to x=1
1 x
這樣設方程式不知道對不對 ∫ e -x^1/2 dx
0
是非題
b
1. ∫|f(x)dx>0 , for any a=/=b
a
n
2. n!>a for any positive real number a as n->oo
n
3.f(x)=x ,we can find the extremun on R at least one point for any positive
integer n
煩請各位版有指導
感謝
