सिद्ध कीजिए - `(sin A )/(sec A+tan A-1)+(cos A)/(cosec A+cot A-1)=1`

(sin A)/(sec A+tan A-1)+(cos A)/(cos ecA+cot A-1)=1

Prove that (sin A)/(sec A + tan A -1)+ (cos A)/("cosec "A +cot A-1)=1

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

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

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

" (i) "(1+sec A+tan A)(1-cosec A+cot A)=2

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

(1+tan A)/(sin A)+(1+cot A)/(cos A)=2(sec A+cosec A)

Prove that (i) (tan A+ sin A)/(tan A- sin A)= (sec A+1)/(sec A-1) (ii) (cot A- cos A)/(cot A+ cos A)= ("cosec" A-1)/("cosec" A+1)

(1+tan A+sec A)(1+cot A-cosec A)=
