(2y-1)/6-(4y+1)/8=1(2y-1)/6-(4y+1)/8=1(2y-1)/6-(4y+1)/8=1(2y-1)/6-(4y+1)/8=1两边同时乘以24得:4(2y-1)-3(4y+1
(2y-1)/6-(4y+1)/8=1
(2y-1)/6-(4y+1)/8=1
(2y-1)/6-(4y+1)/8=1
(2y - 1)/6 - (4y + 1) /8 = 1
两边同时乘以 24 得 :
4(2y - 1) - 3(4y + 1) = 24
8y - 4 - 12y - 3 = 24
12y - 8y = -4 - 3 - 24
4y = -31
y = -31/4
y (3y^2+8y-3)-6y(3y+2y-1)+9y
[T,Y]=ode45(@rigid,[0 1],[rand(15,1)]);plot(T,Y(:,1),'-',T,Y(:,2),'-.',T,Y(:,3),'.',T,Y(:,4),'-',T,Y(:,5),'-.',T,Y(:,6),'.',T,Y(:,7),'-',T,Y(:,8),'-.',T,Y(:,9),'.',T,Y(:,10),'-',T,Y(:,11),'-.',T,Y(:,12),'-.',T,Y(:,13),'.',T,Y(:,14),'-',T,Y(:,15),'.')
y- 2y+1/2=9- 8-y/4
y-2y+1/2=9-8-y/4
2-(4-y)=6y-2(y+1)
2-(4-y)=6y-2(y+1)
y-2[y-4(y-1)]-8=0
常微分方程的通解dy/dx=(x-y+1)/(x+y-3)y^4=2y^n+y=0y''+6y'+9y=e^(-3x)y''+y'-2y=4e^(2x)
(y-2)(y^2-6y-9)-y(y^2-2y-15),其中y=1/2.先化简再求值.
方程y''-4y'+13y=0的通解方程y''=(1+y'*y')/2y的通解
4y(y-1)=3 3y^2+2√6y=-2
{3(x+y)-4(x-y)=4 {x+y/2 + x-y/6=1
解3y+5/3y-6=1/2+5y-4/2y-4
急,看不懂问我(y+3)^2/8-y=(y+3)/4-(y-1)/2
(3y-1)(2y-3)+(6y-5)(y-4)=?xie
(3y-1)(2y-3)+(6y+5)(y-4)=?
(y+1)分之(2y+3)=(3y+4)分之(6y+7)
(2y-1)/6-(4y+1)/8=1
