Show that each of the following statements is an identity by transforming the left side of each one into the right side: 43. cos tan = sin 44. sin cot = cos 0 45. sin 0 sec 8 cot 0 = 1 46. cos 0 csc 0 tan 0 = 1 CSC 8 47. = sec 0 sec 0 cot 48. = csc 0 tan 0 sec 0 49. =tan 0 CSC 0 CSC 0 50. = cot sec 0 51. sin tan 0+ cos 0 sec 53. tan + cot = sec 0 csc 0 52. cos cot + sin 0 = csc 0 54. tan20+1 = sec0 55. csc-sin 0 = cos20 sin 56. sec - cos 0= sin20 cos B 57. 1-sin20= cos 20 58. 1 cos20 = sin0
