([" (i) "(cos A-sin A+1)/(cos A+sin A-1)=cosec A+cot A" ,using "],[," (vin "A" t tan A "]

(cos A-sin A + 1) / (cos A + sin A-1) = csc A + cot A

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

Prove that: (cos A - sin A + 1)/(cos A + sin A -1) = "cosec"A + cot 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 .

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

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

(1 + cot A + tan A) (sin A-cos A) = sin A tan A-cot A cos A

Prove that : (cos A cot A)/ (1 - sin A) = 1 + cosec A

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