Please help with this one. I've worked it out in so many ways and can't tell what's correct.
----- - ------
Which answer is correct for the problem above?
b) sinA tanA
d) secA cscA
common denominator: 1-sin^2 A
and that is equal to cos^2 A.
sinA-sin^2A - sinA -sin^2 A
-2sin^2A /cos^2 A and you recall that tan u= sinU/cosU
