4 (4y-y^2)^(1/2) ∫∫ x^2 dxdy 0 0 麻煩各位了謝謝 -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 61.217.101.47

推 TBEX:是轉成這樣吧 0<= R <=4sinθ 0<= θ <=π/2218.184.164.225 07/13

推 qqoodb:請問你怎麼轉的啊?? 謝啦 59.115.72.39 07/13

推 TBEX:0<= y <=4 0<= x <= (4y-y^2)^(0.5) 畫出來看吧218.184.164.225 07/13

推 qqoodb:我懂了謝謝你~~~ 59.115.72.44 07/14
