I need #24-42 only even numbers solved. Al the work shown.

20. y2 - 2x - 4y - 1 = 0, (-2, 1) 21. 6x2 + 3xy + 2y2 + 17y - 6 =0, (-1, 0) 22. x2 - V 3xy + 2y2 = 5, (V3, 2) 23. 2xy + 7 sin y = 21, (1, 1 / 2) 24. x sin 2y = y cos 2x, (1/4, TT/2) 25. y = 2 sin (Tx - y), (1, 0) 26. x2 cos2 y - sin y = 0, (0, TT) In Exercises 27-30, use implicit differentiation to find dy/dx and then d2 y/ dx2. equation 27. x2 + y2 = 1 You can 28 . * 2/3 + 1 213 = 1 29. y2 = x2 + 2x dail 30. y2 + 2y = 2x+ 1 In Exercises 31-42, find dy/dx. arpaised by this derivati. 31. y = x9/4 conjecture abo 32. y = x-3/5 33. y = VX living 0? Do 34. y = Vxton enable 35. y = (2x + 5)-1/2 fuch? 36. y = (1 - 6x) 2/3 37. y = xVx2+ 1 the whose 38. y = Vx2 + 1 39. y = V1 - Vx 40. y = 3(2x-1/2 + 1)-1/3 41. y = 3(csc x) 3/2 42. y = [sin (x + 5) 15/4
