Methods of Proving Trigonometric Identities (1 Viewer)

Some very unthoughtful responses. Any means of equivalence will suffice. Make sure in your first line you write something like:

"This is equivalent to showing that:"

and you'll be perfectly fine. LHS-RHS is particularly useful for inequalities.

show you can use the end result to help you, with prove you can't. dun goofed.

and with inequalities, generally you would consider the difference anyway

LHS - RHS = 0 iff LHS = RHS. ie. they are the same thing. And yes this does come in handy for inequalities (4U) as gurmies said.
