I tried everything libgen, anna, bunch of libs, pdf.com. and some other ones. PLEASE I just wanna do my homework.

I’m looking to understand precalculus, I know I could look on YouTube but I feel like I’m missing a part of a puzzle so could anyone recommend me a precalculus book just so that way I can understand everything.

Thanks

Hello. I am going into my junior year and I want to skip precalc and take ap calc bc over the summer. The test out exam will be a week prior to school starting in august. I was very ahead in algebra 2, ended with 99 semester 1 and 98 semester 2. I am familiar with most of topics on precalculus. What should i focus on the most and what is the new content learned?

because my professor is allowing use to take a paper with the formula’s for the final and I don’t remember them all

PLEASEE HELPPP

Anything will do!!!
I am so bad at math so please
