x+y+z=0,x^2+y^2+z^2=1求dx/dzx+y+z=0,x^2+y^2+z^2=1求dx/dzx+y+z=0,x^2+y^2+z^2=1求dx/dzx+y+z=0对z求导dx/dz+dy
x+y+z=0,x^2+y^2+z^2=1求dx/dz
x+y+z=0,x^2+y^2+z^2=1求dx/dz
x+y+z=0,x^2+y^2+z^2=1求dx/dz
x+y+z=0
对z求导
dx/dz+dy/dz+1=0
x^2+y^2+z^2=1
对z求导
2x*dx/dz+2y*dy/dz+2z=0
联力上面两个方程
解得:
dx/dz=(y-z)/(x-y)
已知:x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值.
x^2/(z+y)+y^2/(x+z)+z^2/(x+y)=0,求x/(z+y)+y/(x+z)+z/(x+y)的值
证明 :x/(y+z)+y/(z+x)+z/(x+y)>=3/2其中 x,y,z>0
用行列式的性质证明:y+z z+x x+y x y z x+y y+z z+x =2 z x y z+x x+y y+z y z x 这个怎么证?
(x-2y+z)(x+y-2z)分之(y-x)(z-x) + (x+y-2z)(y+z-2x)分之(z-y)(x-y) + (y+z-2z)(x-2y+z)分之(x-z)(y-z)=?第三部分那个是 (y+z-2x)(x-2y+z)分之(x-z)(y-z)
试证明(x+y-2z)+(y+z-2x)+(z+x-2y)=3(x+y-2z)(y+z-2x)(z+x-2y)
已知(x+y)(x+z)=x,(y+z)(y+x)=2y,(z+x)(z+y)=3z,求x,y,z
x>=y>=z>0,求证:x^2*y/z+y^2*z/x+z^2*x/y>=x^2+y^2+z^2
已知(x+y+z)^2=x^2+y^2+z^2,证明x(y+z)+y(z+x)+z(x+y)=0
已知x-y/x+y=y+z/2(y-z)=z+x/3(z-x),求证8x+9y+5z=0THX..
已知x、y、z满足方程组:x+y-z=6;y+z-x=2;z+x-y=0 求x、y、z的值
已知X.Y.Z满足方程组,X+y-Z=6y+z-x=2z+x-y=0求X.Y.Z的值
已知x,y,z 大于0,x+y+z=2,求证 xz/y(y+z)+zy/x(x+y)+yx/z(z+x)大于等于2/3
2x+z=10 x+y-z=4 3x-y-z=0
若|x+3|+|y-2|+|2×z+1|=0求(x×z-y×z)(y-x+z)的值
1998(x-y)+1989(y-z)+1990(z-x)=0,1998^2(x-y)+1989^2(y-z)+1990^2(z-x)=1989,求z-y
(x+y-z)^2-(x-y+z)^2=?
(x-y-z)*( )=x^2-(y+z)^2 填空
