(1-x^2)^1/2*y'-(1-y^2)^1/2=0用分离变量法求该方程通解
(1-x^2)^1/2*y'-(1-y^2)^1/2=0用分离变量法求该方程通解
(1-x^2)^1/2*y'-(1-y^2)^1/2=0用分离变量法求该方程通解
∵∫dx/√(1-x²)=arcsinx+C (C是积分常数)
∴由(1-x²)^1/2*y'-(1-y²)^1/2=0
==>dy/√(1-y²)=dx/√(1-x²)
==>arcsiny=arcsinx+C
故 原方程的通解是arcsiny=arcsinx+C (C是积分常数).
[(-x-y)(-x+y)-(x+y)^2-x(y-y^2)}÷1/2y
1、y-x/x²-y²2、(x-y)(y-z)(z-x)/(z-y)(y-x)(x-z)
(x-y)(2x-y-1)
[(-2x-y)^2-(2x+y)(2x-y)]÷2y-1/2y
2y(x+二分之一y)-[(x+y)(x-y)+2y(y+x)],其中|x-1|=2
(x-y)(x+y)-(x+y)^2+2y(y-x),其中x=1,y=3.
求(1+y)-2x(1+y)+x(1-y)
把4(x-y+1)+y(y-2x)因式分解
y(y+2)+4x(x-y-1)因式分解是多少
(x-y/1-x+y/1)÷2y/y-x计算错了,是(1/x-y-1/x+y)÷2y/y-x
(x/x+y-x/y-x-2xy/x.x-y.y)/(1/x-1/y) 分式化简
x²/xy-x/y 3x/4x+y - x-2y/4x+y (1-y/y+x)÷x/y²-x²
对于(y一撇)y`=y/x(y-1)求导,我求的结果是y``=-y^2-y`x+y/x^2(y-1)^2 怎么不对啊,我的求导过程是:y`x(y-1) - [x(y-1)]` y y`xy-y`x-(y-1+xy`)y -y^2-y`x+yy``=-------------------------=----------------------=-----------------x^2 (y-1
已知x+y=a,2x-y=-2a,求[(x/y-y/x)/(x+y)-x(1/x-1/y)]/[(x+1)/y]的值
若2/x-1/y=3,求[y/x-y/x-y(x-y/x-x+y)]/x-2y/x的值
化简(2x+y)(2x-y)-(x+2y)(x-2y-1)
x+2y=2x+y+1=7x-y 求:2x-y?
设x,y满足约束条件x+y>=1,x-y>=-1,2x-y
