SinA = 1/3 = Opposite/Hypotenuse
Therefore taking Opposite to be 1cm and Hypotenuse to be 3cm.
Therefore Adjacent side = Root of 32 - 12
= root 8
CosA = Adjacent/Hypotenuse = root8 / 3
CosecA = Hypotenuse/Opposite = 3/1
TanA = Opposite/Adjacent = 1 / root8
SecA = Hypotenuse/Adjacent = 3 / root8
Therefore,
(CosA.CosecA) + (TanA.SecA) = (root8 / 3 . 3 / 1) + (1 / root8 . 3 / root8)
= (root8) + (3 / 8)
= 2(root2) + (3 / 8)6 + 12 - 5 = 13
It should be evaluated as a major calculation error!

4+1=5. Plus 4 equals 9. Plus 77685769844446473 equals 77685769844446482. Plus 3 equals 77685769844446485. Plus 8 equals 77685769844446493. Plus 1 equals 77685769844446494. Plus 9870998342523322424 equals 1064785604097768918. Plus 4 equals 1064785604097768922.
CosecA + CotA = 11/2Cosec2A - Cot2A = 1 {By the Identity}(CosecA + CotA) (CosecA - CotA) = 111/2 (CosecA - CotA) = 1(1/SinA) - (CosA/SinA) =2/11(1 - CosA) / SinA = 2/11Therefore 1 - CosA = 2CosA = 3 and SinA = 11Therefore TanA = SinA / CosA = 11/3
