cosec a + cot a = 11/2
cosec a - cot a = 1 / (cosec a + cot a) ...from cosec^2 - cot^2 = 1
cosec a - cot a = 2/11
subtract both the equation
2 cot a = 11/2 - 2/11
2 cot a = 117/22
cot a = 117/44
tan a = 44/117

‼
cosec A + cot A = 11 / 2
cosec A = 11 / 2 – cot A
cosec²A = ( 11 / 2 – cot A )²
cosec²A = 121 / 4 + cot²A – 11 cotA
cosec²A – cot²A = ( 121 – 44 cot A ) / 4
1 = ( 121 – 44 cot A ) / 4
4 = 121 – 44 cot A
44 cot A = 121 – 4
44 cot A = 117
cot A = 117 / 44
cot A = 1 / tan A
tan A
cosec A + cot A = 11 / 2
cosec A = 11 / 2 – cot A
cosec²A = ( 11 / 2 – cot A )²
cosec²A = 121 / 4 + cot²A – 11 cotA
cosec²A – cot²A = ( 121 – 44 cot A ) / 4
1 = ( 121 – 44 cot A ) / 4
4 = 121 – 44 cot A
44 cot A = 121 – 4
44 cot A = 117
cot A = 117 / 44
cot A = 1 / tan A
tan A
