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

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

Prove that (sec A-cosec A)(1+tan A+cot A)=tan A secA + cotA cosec A

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

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

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

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

Prove that : 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+cosec 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)
