: सिद्ध कीजिए कि cot A-cos A cosec A-1 cot A + cos A cosec A +1

cosec A- 2cot 2A cos A=

cosec A -2 cot 2A cos A=

(cosec A)/(cot A+tan A)=cos A

Prove the following : (cot A - cos A)/(cot A + cos A) = (cosec A -1)/(cosec A + 1) .

Show that (cot A - cos A)/(cot A + cos A) = ( cosec A - 1)/(1 + cosec A)

sin A(1+tan A)+cos A(1+cot A)=sec A+cosec A

Prove the following identities : (1 + sin A)/ (cosec A - cot A) - (1 - sin A)/ (cosec A + cot A) = 2(1 + cot A)

7. (sin A+cos A)(cot A+tan A)=sec A+cosec A

( cos A - sin A + 1 ) / ( cos A + sin A - 1 ) = cosec A + cot A cosec A + cot A , = using the identity cosec ^ 2 A = 1 + cot^ 2 A .
