Find a general solution to each first - degree ordinary differential equation. If an initial condition is given, find the corresponding particular solution. Write all solutions explicitly if possible. Solve all a.
(dr)/(d\theta )=(r^(2))/(\theta )
b.
y^(')=(1-y)cos(x),y(\pi )=2
c.
2xy(dy)/(dx)=4x^(2)+3y^(2)
d.
(9x^(2)+y-1)dx-(4y-x)dy=0,y(1)=0
e.
(dy)/(dx)=ry-ky^(2),
where
r
and
k
are constants,
r>0
f.
(dx)/(dt)=\sqrt(x+t+1)
g.
(3xy+y^(2))+(x^(2)+xy)y^(')=0
