Obviously you should go read a book on what your want to know, you fucking retard. How stupid can you be to seriously ask how to relearn something you learned from a book in the first place?

I just finished precalc in my first semester at uni with the book Precalculus: Mathematics for Calculus, 5th Edition (ISBN-13: 978-0495557500) and while I can't say it's the greatest precalc book, it was good to review with. It's really cheap too

what did you forget? I dont even know what precalc knowledge is. most calc books go through shit you need

Precalc is pretty much a lot of algebra and logarithms, I think

>>7784817
from conics to other formulas
most importantly analyzing functions? i should say
like finding vertical asymptotes and horizontal
other trigonometry functions.
I should just find my old SAT prep book and study again
but idk how im going to study precalc material along with calc, plus other classes, and work
and unfortunately i got community hours to do
damn i love my life

yeah that too..

Wouldn't Khan Academy be good enough for remembering?

OP do yourself a favor and get "Pre-calculus" by Axler. If you still can't understand after working through that book, maybe mathematics isn't for you
