推 skyword:1.畫圖 2.換序積分 219.85.43.250 07/07 19:15
推 chemical1223:y=x^2 y=1 x=0 x=1 畫出圖形 59.117.187.72 07/07 22:41
→ chemical1223:先機歪，所以是從x^2 → 1 59.117.187.72 07/07 22:42
→ chemical1223:再積X 所以是從0→1 59.117.187.72 07/07 22:42
→ chemical1223:第二、三推文是找出原本的積分範圍 59.117.187.72 07/07 22:43
→ chemical1223:交換積分次序後 會變成0→根號y 59.117.187.72 07/07 22:43
→ chemical1223:和 0→1 59.117.187.72 07/07 22:43
