" (iv) "tan B+cot B=sec B cosec B

If sin(A+B)=1 and tan(A-B)=1/sqrt(3) , find the value of: (i) tan A + cot B (ii) secA-cosec B

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

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)

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

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

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

If A+B=90 then prove that sqrt((tan A tan B+tan A cot B)/(sin A sec B))=sec A

if a+b=90^(@) then prove that sqrt((tan A tan B+tan A cot B)/(sin A sec B))=sec A

If A + B = 90^(@) , prove that sqrt((tan A tan B + tan A cot B)/(sin A sec B ) - (sin^(2) B)/(cos^(2)A)) = tan A .

If A+B=90^(0), prove that sqrt((tan A tan B+tan A cot B)/(sin A sec B)-(sin^(2)B)/(cos^(2)A))=tan A
