2x^3+3y^3=5,求y''''求二次导,谢谢!2x^3+3y^3=5,求y''''求二次导,谢谢!2x^3+3y^3=5,求y''''求二次导,谢谢!2x^3+3y^3=5两边同时对x求导,得6x^2+9y
2x^3 + 3y^3 = 5,求y''求二次导,谢谢!
2x^3 + 3y^3 = 5,求y''
求二次导,谢谢!
2x^3 + 3y^3 = 5,求y''求二次导,谢谢!
2x^3 + 3y^3 = 5
两边同时对x求导,得
6x^2+9y^2·y'=0
y'=-2x^2/3y^2
y''=-(4x·3y^2-2x^2·6y·y')/9y^4
=-(12xy^2-12x^2y·(-2x^2/3y^2))/9y^4
=-(12xy^2+(8x^4/y))/9y^4
=-(12xy^3+8x^4)/9y^5
已知x-y/x+y=3,求代数式5(x-y)/x+y-x+y/2(x-y)
(x-y)/(x+y)=3求( 3x-2y-1)/(x+y-5)
已知:3x-5y=0,求x/y,x-y/y,x-y/x
{(x+y)/2+(x-y)/3=1,(x+y)-5(x-y)=2.求x=?,y=?
5X+Y=3 X+5Y=2 求x和y.5X+Y=3X+5Y=2求x和y.
已知x-y=3,求[（x+y)(x-y)-(x-y)^2+2y(x-y)]除以的值
已知3x =2y 求x/x+y+y/x-y-y²/x²-y²
y=x^3-5x^2+2x-8 求y^2求y撇
6x+5Y=31 2X+3Y=17求X求 Y
若x-y/x+y=5,求x-y/2x+2y+5x+5y/3x-3y的值
若x+y分之x-y=3,求式子x+y分之5(x-y)—2(x-y)分之x+y的值
若x-y分之x+y=3,求式子x+y分之5(x-y)—2（x-y）分之x+y的值
已知|x|=2,|y|=3,|x+y|=-(x+y)求x-y
y=3(x-y),x=2(x-y)求x,y的值
y''-3y'+2y=x^3 求通解
求y''+3y'+2y=e^x
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
2x+3y/5x-3y=3/5求x/y的值
