求曲线所围图形的面积(x^2+y^2)^2=a(x^3-3xy^2),a>0
举一反三
- 求由抛物线y=x 2 , x=3, y=0所围图形的面积。
- x^2+y^2-4x-6y+13=0,求(2/3根号9x+y^2根号x/y^3)-x^2根号1/x-5x根号y/x)的值
- 分解因式()x()3()y()-()2()x()2()y()2()+()xy()3()正确的是A.()xy()(()x()+()y())()2()B.()xy()(()x()2()﹣()2()xy()+()y()2())()C.()xy()(()x()2()+2()xy()﹣()y()2())()D.()xy()(()x()﹣()y())()2
- 求曲线z=根号(4-x^2-y^2)与z=根号3(x^2+y^2)所围立体体积
- 求由抛物线y=x 2 , 00a0x=3, y=0所围图形的面积。
