Not Exact 3. x3 - x2 y + 2x + 2y 3 + 3y = c 4. x2 y 2 + 2xy = c 5. ax2 + 2bxy + cy 2 = k 6. Not Exact 7. ex siny + 2ycosx = c; also y = 0 8. Not Exact 9. exy cos2x + x2 - 3y = c 10. y ln x + 3x62 - 2y = c 11. Not Exact 12. x2 + y 2 = c 1 13. y = 14. y = x+ 28-3x2 , 2 |x| < 28 3 x- (24x3 +x2 -8x-16) , 4 x > 0.9846 15. b = 3; x2 y 2 + 2x3 y = c 16. b = 1; e2xy + x2 = c 2 ...
