Question

Prove The identity:

SecX-TanX=1-SinX/CosX

Answer 1

that's not right

Answer 2

Nope, it sure isn't

Answer 3

secx-tanx
=1/cos(x) - sin(x)/cos(x)
=(1-sinx)/cos(x)

The question is missing parentheses, should read:
SecX-TanX=(1-SinX)/CosX

Answer 4

Oh, okay

Answer 5

Well, now, the solution is pretty obvious. I don't know why anyone would be stuck on this for an hour.
