`cot^-1[(cot alpha)^(1/2)]+tan^-1[(cotalpha)^(1/2)]=x then sin x=` (A) 1 (B) `cot^2(alpha/2)` (C) `tanalpha` (D) `cot(alpha/2)

If cot^(-1)(sqrt(cos alpha))-tan^(-1)(sqrt(cos alpha))=x then sin x is tan^(2)(alpha)/(2)(b)cot^(2)(alpha)/(2)(c)tan^(2)alpha(d)cot(alpha)/(2)

cot^(-1)((alpha)/(2))-tan^(-1)(sqrt(cosalpha))=x , then sin x is equal to

if cot^(-1)[sqrt(cos alpha)]-tan^(-1)[sqrt(cos alpha)]=x then sin x is equal to

If tan alpha+cot alpha=2 then

cot_(sin x)^(-1)(sqrt(cos alpha))-tan^(-1)(sqrt(cos alpha))=x then

If: cot^(-1)alpha + cot^(-1)beta = cot^(-1) x , then: x=

If quad cot^(-1)sqrt(tan alpha)-tan^(-1)sqrt(tan alpha), then tan ((pi)/(4),(u)/(2))i sequa<0 (a) sqrt(tan alpha)(b)sqrt(cot alpha)(c)tan alpha(d)cot alpha
