[微積] find the area

[kelvin811 (sheila)]

1.find the area of the region between the curve y=3-x^2 and the line y=-1

2.find the area of the triangular region in the first quadrant that is
  bounded above by the curve y=e^(2x) below by the curve y=e^(-x/2),
  and on the right by the line x=2*ln2

→ fermion     :這兩題應該很基本喔,Int[dxdy]上下限設一下就ok啦
→ kelvin811   :我有嘗試算了...可是好像哪裡怪怪的
推 vicwk       :(1)直接平移成y=4-x^2然後-2積到2 (2)e^(2x)積分減去
→ vicwk       :e^(-x/2)積分 0積到2ln(2)
→ kelvin811   :謝謝~~我積出來了!!
