推 GBRS:1.形如f(x)=cx+d的函數稱為linear function 211.76.58.233 05/31 00:05
→ GBRS:所以兩次微分後為0,積分當然也是0 211.76.58.233 05/31 00:05
b
1.if f is a linear function and 0<a<b, then ∫ f''(x)dx=
a
(A)0 其他答案不打了 答案寫這個 不太懂
2.which of th following is an equation of the line
tangent to the grapg of f(x)=x^4+2x^2 at the
point where f'(x)=1?
(a)y=8x+5 (b)y=x+7 (c)y=x+0.763 (d)y=x-0.122 (e)y=x-2.146
答案是D 不太懂題目的意思
3.if 0<=k<π/2 and the area under the curve y=cosx from
x=k to x=π/2 is 0.1, then k=
(a)1.471 (b)1.414 (c)1.277 (d)1.120 (E)0.436
這個是要估計sink=0.9的k值嗎? 如果是的話我算不出來...
答案是D
3題請大家幫我看一下 謝謝囉
