公式可以的，前提你會參數化就好. 圓心偏移的參數化. x = r cost + a. y = r sint + b. r = √337/4. a = √81/4 = 9/2. b = √64 = 8. D =0.5∫(-ydx+xdy). = 0.5 ∮ -(r sint + b) (-r sint

→ → →. For a vector function F(x,y,z) = F1 i F2 j F3 k,it is known that. → → →. curf F=(- 4y^3 z^6 - 4x^5 y^2)i-4z^3j+(20x^4 y^2 z-3x^2 y^2)k. div F=
