If a presentation features numerous slides in a row that all have the same general look and a user needs to see the slides
and reorder them based on the text in their headings, which method would be the most advantageous for the user?

The sin(A) goes with 'a'

sin(B) goes with b

sin(C) goes with c

Each angle goes with the corresponding side to form the three fractions shown. You can break up that triple equation into smaller equations such as and and

Note: if you apply the reciprocal to all three sides, then you'll get an equivalent equation. I'm using the rule that A/B = C/D is the same as B/A = D/C.
