Hi,
   
  It will be really helpful if someone could solve the below problems.
  Thanks in Advance.
   
   
  1) Given that y is always positive and y(0) = 2. By direct integration method, find the
particular solution of the differential equation
  dy/dx=y(1-y)/(y+1)
  Hence show that y2-y(2+1/2e-x)+1=0
   
  2)Using substitution method, find the general solution of the following homogeneous
differentiation equation
  dy/dx=(y/x)/1+(y/x)2
  Hence find the particular solution if y(4)=2.
   
   
  Regards,
  Anooja
