`(tan A+ cosec B)^(2)-(cot B - sec A)^(2)=2 tan A cot B(cosec A + sec B)`

(tan A+cos ecB)^(2)-(cot B-sec A)^(2)=2tan a cot B(cos ecA+sec B)

Prove (tan A + cos ecB) ^ (2) - (cot B-sec A) ^ (2) = 2tan A cot B (cos ecA + sec B)

(tan A+cot A)=(sec A*csc A)

Prove the following identities: (1+tan A tan B)^(2)+(tan A-tan B)^(2)=sec^(2)A sec^(2)B(tan A+csc B)^(2)-(cot B-sec A)^(2)=2tan A cot B(csc A+sec B)

(1 + cot A — cosec A) (1 + tan A + sec A) = 2 .

Prove that : sqrt (sec^(2) A + cosec^(2) A) = tan A + cot A

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

tan B+cot B=2sec2A rArr A+B=

Prove that : (sec A - cosec A ) (1 + tan A + cot A)= tan A sec A-cot A cosec A .
