" 8."sin^(-1)(cos x)+tan^(-1)(cot x)

sin^(-1)(sin x)=x;cos^(-1)(cos x)=x;tan^(-1)(tan x)=x;cot^(-1)(cot x)=x;sec^(-1)(sec x)=x;cos ec^(-1)(cos ecx)

If x ne n pi, x ne (2n+1) (pi)/(2) n in Z, then : sin^(-1) ((sin^(-1) (cos x) + cos ^(-1) (sin x))/(tan^(-1) (cot x) + cot^(-1) (tan x )))=

sin(Cot^(-1)(cos(Tan^(-1)x)))=

sin[cot^(-1){cos(tan^(-1)x)}]=
