LS = sec^2 x - 1 , (did you notice the difference of squares pattern ?)
= tan^2 x , by definition
= RS
for (sec x -1)(sec x + 1) = tan^(2) x
so far I got up to:
(sin^(2)x / cos x) (-sin^(2)x / cos x)
what would the next step be?
steps too please

I don't get how you got to sec^2x - 1
where did the 1 come from
