Step-by-step explanation:

We have,

y \sin(2x) dx - (1 +  {y}^{2}  +  \cos^{2} (x) )dy = 0 \\

 \implies \: y \sin(2x) dx -  \cos ^{2} (x) dy = (1 +  {y}^{2} )dy \\

 \implies - ( \cos^{2} (x) dy - y \sin(2x) dx) = (1 +  {y}^{2} )dy \\

 \implies \:  - d( y.\cos^{2} (x) ) = (1 +  {y}^{2} )dy \\

Integrating both sides,

 \implies \:  \int - d( y.\cos^{2} (x) ) = \int (1 +  {y}^{2} )dy \\

 \implies \: y  \cos^{2} (x) = y +  \frac{ {y}^{3} }{3}   + c \\
