Answer: given, cosec(tan −1 (cos(cot −1 (sec(sin −1 a))))) =cosec(tan−1 (cos(cot −1 (sec(sec −1 1−a 2 1 ))))) {Since for a∈[0,1],sin −1 a=sec −1 1−a 2 1 ] =cosec(tan −1 (cos(cot −1 1−a 2 1 ))) =cosec(tan −1 (cos(cos −1 2−a 2 1 ))) [Since for a∈[0,1],cot −1 1−a 2 1 =cos −1 2−a 2 1 ] =cosec(tan −12−a 2 1 ) =cosec(cosec −1 3−a 2 ) [Since for a∈[0,1],tan −1 2−a 2 1 =cosec −1 3−a 2 ] = 3−a 2 .
