" If "cot^(-1)(sqrt(cos alpha))-tan^(-1)(sqrt(cos alpha))=u," then sinu is equal to "

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

Cot^(-1)(sqrt(Cos alpha))-Tan^(-1)( sqrt(Cos alpha))=x then Sinx=

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(sinalpha))+tan^(-1)(sqrt(sinalpha))=u,"then"cos2u"is equal to"

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)
