CosecA+Cot A=11/2.
Then find TanA?

We have,cosec A + cot A = 112   ....1Now, cosec2A - cot2A = 1cosec A + cot Acosec A - cot A = 1112cosec A - cot A = 1cosec A - cot A = 211    ......2Subtracting 2 from 1, we get2 cot A = 112 - 2112 cot A = 121 - 422cot A = 11744tan A = 1cot A = 44117

is the answere
  • -1
cosec A + cot A = 11/2            ... (1) (cosec A + cot A) x (cosec A - cot A)/(cosec A - cot A) = 11/2
(cosec 2a - cot^2 A) /(cosec A - cot A ) = 11/2
Now cosec^2 A - cot^2 A = 1
Therefore, 1/(cosecA - cotA) = 11/2 cosec A - cot A = 2/11             ... (2)
From (1) and (2), we get,
- 2 cot A = 2/11 -11/2 = -117/22
cot A = 117/44
Therefore, tan A = 1/cot A = 44/117
