Solve the following differential equation and sketch the solution curves:

       

Solution:               

 

1.     Rewrite equation in normal form:

           

1st order, non-linear, non-separable

check for exact:

 

2.     Rewrite equation in standard differential form:

Not exact.  Try for integrating factor:

          function of y only

Then integrating is
