trig identities is easy.
i usually study in this pattern, do 1 question, check the back of the book for that one. if i am wrong, i find out why, and i write a note beside the question what should i have done.
i sticky note my notes and so i can get to it faster than skimming through them every time.
once you memorize all the trig identities, it's a walk in the park. search profrobbob on youtube. i use his videos for stuff i don't understand.

this is what i say to myself everytime i do my homework. and when i get to questions i don't understand or solve them incorrectly, i resort to the back of the book, and it refreshes my memory. then i'll say, "oh i knew that".
do your homework, every single question. do it from the last to the first, because the last usually are the hardest.
find out why you didn't get it right, it's important to understand why. identify the question to what kind of problem it is and what formula you need to use to solve it.
i don't know if you've done it yet, but you'll soon have to prove (sinēө)(sinēө) + (cosēө) / cotēө) and that is when you really need to understand trig identities.
