यदि ` x =(1+ sin A) /( cos A) ` तो सिद्ध कीजिए की ` (1)/(x) =(1- sinA) /( cos A) `

1- (sin ^ (2) x) / (1 + cos x) + (1 + cos x) / (sin x) - (sin x) / (1-cos x) =

Prove that (1 + sin x-cos x) / (1 + sin x + cos x) + (1 + sin x + cos x) / (1 + sin x-cos x) = 2cos ecx

(sin A)/(1+cos A)+(sin A)/(1-cos A) is (0^@ (0^@ < A<90^@) की स्थिति में (sin A)/(1+cos A)+(sin A)/(1-cos A) कितना होगा?

Prove that (sinA -cos A+1)/(sin A + cos A - 1) = (1)/(sec A - tan A)

'solve tan ( sin − 1 ( cos ( sin − 1 x ) ) ) tan ( cos − 1 ( sin ( cos − 1 x ) ) ) '

The maximum value of cos x ((cos x )/( 1- sin x) + (1- sin x)/( cos x) ) is

सिद्ध कीजिए कि 2tan^(-1)sqrt((b)/(a))=cos^(-1)((a-b)/(a+b))

The value of ((sin A)/(1-cos A)+(1-cos A)/(sinA) div ((cot^2 A)/(1+cosec A)+1) is:

Prove that : (1+ cos A)/(sinA) + (sin A)/(1+ cos A) = 2 "cosec " A

int (sin ^ (- 1) x-cos ^ (- 1) x) / (sin ^ (- 1) x + cos ^ (- 1) x) dx =
