Is there and easier way to do trig identities?
Any hints or tips?

sin(x) cos(x) tan(x) cot(x) sec(x) csec(x)
These are the basic level 1 (just kidding but if you got that you got 40% of the bulk)
Knowing that puts you into 65-70th percentile.
Then you use these to derive additional 10-15%
sin(x+y)=? see rteference or math tables

Start on the side that looks the most complicated.
Use well know identities that help you to isolate to just a single trig function.
Just keep trying and you'll get it finally.

tanx,cotx,cosecx, secx, sin2x, cos2x

clever way- (a+b)^3
=we can multiply each to get the formula
