Answer:
sinA-CosA=0
SinA=cosA
now,
secA+cosecA
=1/cosA+1/sinA
=(cosA+sinA)/cosA×sinA
now putting the value of sinA in this equation,
2cosA/cosA×cosA
=2/cosA
=2secA
you can also put sinA at the place of cos A

Answer:
SinA - CosA = 0...
SinA = CosA...
So.... SinA/CosA = 1...
So... TanA = 1...
And therefore A = 45 degree...
So SecA + CosecA = 2(2^1/2)....
