I need to gain a good foundation for math. I have 5 months until I need to either be enrolled in Calc I or kill myself. I cruised through math in hs but that was 10 years ago and I forgot it all, probably due to brain changes associated with untreated clinical depression.

Can you recommend me some good books? I've been learning on schoolyourself.org but it's not comprehensive. I need Algebra, Trig, and Geometry. Basically everything up to Calc, and I need to do it in 4 months tops. I saw the wiki but it doesn't seem to be geared towards a brainlet like me.

I took the ALEKS entrance exam and got a fucking 35. I need at least a 76 to enroll in classes.

Apostol's Calculus will help
The 4chan wiki is good for even more basic stuff
take this knowledge and scram because the thread will delete soon

you can skip conic sections, matrices, and probability. complex numbers is optional

When you get to it, don't let calculus scare you or seem like some kind of spooky advanced math, once you know its precursors and the basics its as easy as everything that came before.

>> No.9951989

Just use Khan Academy.
It has literally everything you need.
I'm in a similar situation.

You don't need geometry for calculus. In fact, you don't really need it at all. I'm a senior EE major and have never taken it

Follow khan academy's precalculus tutorial. You don't -need- to enroll in calculus 1 as your first class, though. I started in remedial math (prealgebra, actually. Fucking kek) and finiahed my math reqs (calc 1-3,diffeq, linear algebra, and complex analysis) only a semester behind.

How though? In my gay college there are like two years of maths even before calculus starts. I really don't have the time or the transcript space to be doing that. I'm like you I fucking forgot everything and I'm freaking out a little.

Is Khan comprehensive though?

What exactly are the precursors? Is it mostly trig? I never even took trig while I was in HS.

Basically just get all the resources you need and then grind. Only grit can help you now. Practice is the best way, understanding the concepts alone leads to a shaky foundation, I thought I was a smartass but I got my comeuppance so believe me, I know. This advice applies to other things too.

This is what I'm talking about, friend. That shaky foundation isn't going to fly, and I see that now...which is why I was thinking of working through a few complete textbooks. At least on Algebra and Trig....I guess I should just be looking on my own, I thought friends here could suggest a good one by chance.

Just do algebra problems. PEMDAS and the trig identities, plus how to graph functions, including the trig unit circle. Also factoring. And graphs of y=x, y=x^2, y = x^2 +1 , y=x^3

And memorize the quadratic formula.

In a similar situation here except it's not just math, I've forgotten literally EVERYTHING I learned in high school. To those advocating khan academy for OP, is it good for the other core subjects as well?

For science and engineering, I would say yeah. Thing is, you're gonna want to couple the other subjects with exercises found from somewhere else, because those subjects mostly consist of videos and articles.

Here's the book friend. Honestly this is the best route for you, you'll be ahead for your class and you won't waste time with needless review.
