Answer:

sinA/CosA-cosA/CosA+1/Cosa

_________________________

SinA/CosA+CosA/CosA-1/CosA

= TAN A + SECA- 1

_______________

TANA-SECA+ 1

(tanA+SecA)-(sec2A- Tan2A)

_______________________

tanA-SecA + 1

(TanA+SecA)-[(SecA+ TanA)SecA- TanA)

_________________________________

TanA - SecA + 1

(SecA+ TanA) [1-SecA+ TanA)

________________________

(1-SecA+ TanA)

=SecA + TAN A
