Re: [積分] 兩個積分問題
※ 引述《TaiwanFlight (飛翔吧 ,台灣!!)》之銘言:
: ※ 引述《lkk000966 (Teddy)》之銘言:
: : 1
: : ∫cos(t^2)dt
: : 2
: : ∫dt/(1+t^4)
: http://integrals.wolfram.com/index.jsp
: 這裡是初微版,
: 不要老是出一些初微技巧無法積的東西。
這兩題題目都有上下限
第一題題目應該是==> d/dx ∫cos(t^2)dt 上下限都是x變數 但我忘了是多少
第二題的上下限我忘了
因為我是在無意間圖書館翻到的 所以記不太清楚
很抱歉在這裡問了不是初微的東西 但光看題目我也分不出是不是初微= ="
像第一題我以為用分部積分就可以解決 我以為是我分部積分令錯東西解不出來
