Solutions to (6) sides of packet in order.
Trig identities (1-34)
Trig identities (30-37) with solutions for 1-37
(videos on each of the 37 below if needed)
Notes to start.... on trig identities
Explanation of trigonometric identities here, but at minute 7:56 maybe, I SAID -1, but wrote a 1 :(
A few more to try! (10 examples)
And a few MORE! 20 examples
All of the mega worksheet done out below!(1-37) The 'quality' isnt great, but if you tried the problem...it WILL make enough sense to figure it out!
