Hello,
In my opinion, trigonometry is easy to learn if you focus and try to understand why and what you do when some situation arises.
Firstly, you need to write all the related formulas in one page. All formulas ranging including sin2x, sin3x, tan2x, etc. etc. Then try to memorize them.
Now solve the NCERT book. Remember, when you solve, try to find reason for everything.
For example, if you are writing cos2x as 1-2sin^2x and not like 2cos^2x-1, then find the reason. It is probably because the denominator of the fraction is in terms of sinx. This will let both the terms cancel and make the problem simpler.
All the formulas mentioned in Class 11 and 12 NCERT must be prepared.
Hope this helps.
Thanks.
