Let S be the positively directed curve of the elipse x^2/9 + y^2/4 = 1 Evaluate the line integral ∫ (x^4-3y)dx+(4x+2y^2)dy 知道要用green 定理算 但還是不知道怎球= =? -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 125.229.192.70
LeoRen:旋度是7,7倍的橢圓面積為42pi118.160.181.143 06/27 22:22
LeoRen:不論是green's也好stoke's也好,都一樣!118.160.181.143 06/27 22:22
LeoRen:想一下,這兩個定理是可互通的!118.160.181.143 06/27 22:24
