Question

Prove the following identities, where the angles involved are acute angles for which the expressions are defined. a. cosA/(1+sinA)+(1+sinA)/cosA=2secA. b. (1+secA)/secA=sin2A/(1−cosA) c. √(1 + sinA)/(1−sinA) =secA+tanA PLS WRITE THE CORRECT ANSWER

Answer 1

Answer:

here you have to just use complimentary formula
