[" (c) "[(cos alpha)'/2]-tan^(-1)[(cot alpha)'/2]=x],[" da "sin x=?]

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

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

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)(sqrtcosalpha)-tan^(-1)(sqrt(cos alpha))=x , then sin x is equal to a) tan^2""alpha/2 b) cot^2""alpha/2 c) tan alpha d) cot ""alpha/2

If cot^(-1)(sqrt(cosalpha))-tan^(-1)(sqrt(cosalpha))=x , then sinx is tan^2alpha/2 (b) cot^2alpha/2 (c) tan^2alpha (d) cotalpha/2
