Determine whether the equations are...

Determine whether the equations are exact, If they are solve them:

1) (2ysinxcosx-y+2y^2(e^(x(y^2)))dx = (x-sin^2x-4xy(e^(x(y^2)))dy

2) (2y- (1/x)cos3x) dy/dx + (y/x^2 - 4x^3 +3ysin3x = 0

1) (2ysinxcosx-y+2y^2(e^(x(y^2)))dx = (x-sin^2x-4xy(e^(x(y^2)))dy

2) (2y- (1/x)cos3x) dy/dx + (y/x^2 - 4x^3 +3ysin3x = 0
