Question

Prove that tanA+secA-1/tanA-secA+1=1+sinA/cosA​

Answer 1

Step-by-step explanation:

tanA-1+secA/tanA+1-secA

(tan A+secA)-(sec^2-tan^2A)

____________________________

tan A+1-secA

(tanA+secA)(1-secA+tanA)

__________________________

tanA+1-secA

(tanA-secA)(1-secA+tanA)

_________________________

tan A+1-secA

SecA+tanA

1/cos A + sinA/cosA

1+sinA/cos A
