Find a set of solutions to the following differential equations . 1. ( xy + 1) dx + x y? dy. = 0 2. y ( 2xy + 1 ) dx - xdy = 0 3. xy + Csc (xy) + xy' = 0 4. y ( x2y2 - 1 ) dx + x ( x2yz + 1 ) dy = 0 5. 2x dy = y ( 3x* + yz ) dx 6. y ( y' - x ) dx + x (y + x ) dy = 0 7. y ( x2 + y ) dx + x ( x2 - 2y ) dy = 0 : when x = 1 , y = 2 8. y ( 2 - 3xy ) dx - xdy = 0 9. [ 1 + y tan ( xy ) ] dx + x tan ( xy ) dy = 0 10. x ( x2 - y? - x ) dx - y ( x2 - y? ) dy = 0 ; when x = 2 , y = 0 " Don't say you don't have enough time.
