I would look at (chapters 7,9,10)
https://openstax.org/details/books/algebra-and-trigonometry-2e

You can also find books about Calculus.

Another great resource is

Www.Mathispower4u.com

It has over 5000 video clips for all levels of math from grade school to first year college.

Here is the video library for trig specific problems

https://mathispower4u.com/trigonometry.php

They are grouped by subject and ordered by presentation. You should be able to get help there.
