Please solve 47-79. The odd numbers only. Thank you.

Show that each of the following statements is an identity by transforming the left side of each one into the right side. 47. cos 0 tan 0 = sin 0 48. sin 0 cot 0 = cos 0 49. sin 0 sec 0 cot 0 = 1 50. cos O csc 0 tan 0 = 1 sin 0 51 = sin2 0 52. cos 0 csc 0 = cos2 0 sec 0 . csc 0 53 sec 0 sec 8 cot 0 54. csc 0 tan 0 sec 0 55 tan 0 csc 0 csc 0 56. = cot 0 sec 0 sec 0 cot 0 57. csc 0 tan 0 csc 0 58. 1 sec 0 59. sin 0 tan 0 + cos 0 = sec 0 60. cos 0 cot 0 + sin 0 = csc 0 61. tan 0 + cot 0 = sec 0 csc 0 62. tan2 0 + 1 = sec2 0 63. csc 0 - sin 0 = cos2 0 64. sec 0 - cos 0 = sing 0 sin 0 cos 0 65. csc 0 tan 0 - cos A sin' 0 66. sec 0 cot 0 - sin e - cos2 0 cos 0 sin 0 67. (1 - cos 0)(1 + cos 0) = sin2 0 68. (1 + sin 0)(1 - sin 0) = cos2 0 69. (sin 0 + 1)(sin 0 - 1) = - cos2 0 70. (cos 0 + 1)(cos 0 - 1) = - sin2 0 71. cos 0 sin 0 72. 1 - - sin 0 sec 0 csc 0 = cos2 0 csc 0 73. (sin 0 - cos 0)2 - 1 = - 2 sin 0 cos 0 74. (cos 0 + sin 0)2 - 1 = 2 sin 0 cos 0 75. sin O(sec 0 + csc 0) = tan 0 + 1 76. sec O(sin 0 + cos 0) = tan 0 + 1 77. sin O(sec 0 + cot 0) = tan 0 + cos 0 78. cos 0(csc 0 + tan 0) = cot 0 + sin 0 79. sin O(csc 0 - sin 0) = cos2 0
