व्यंजक `(Cotq+"co s ec"q-1)/(Cotq+"co s ec"q+1)` किसके बराबर होगा ?

cos ec (-1410 ^ (@))

(1+cot alpha+cos ec alpha)/(1-cot alpha+cos ec alpha)

sec^(-1)x+cos ec^(-1)x=(pi)/(2)

(1+cot alpha+cos ec alpha)/(1-cot alpha+cos ec alpha)=

(1+cot alpha+cos ec alpha)/(1-cot alpha+cos ec alpha)=

Which of the following is not equal to (cot theta+cos ec theta-1)/(cot theta-cos ec theta+1)?

Prove that (cot alpha+cos ec alpha-1)/(cot alpha-cos ec alpha+1)=(1+cos alpha)/(sin alpha)

theta=s ec^(- 1)(2/(sqrt(3)))

Number of solutions of the equation cos ec^(-1)(cos ecx)=sin x. in [-2 pi,2 pi] is 'a' and number of solutions of cos ec^(-1)(cos ecx)=sqrt(sin x) in this interval is 'b' then sqrt(a+b) is

sec(cos ec^(-1)x) is equal to : (where |x|>=1)
