Calculus 3

Oh boy, you must be trolling
You have to learn the entire calculus 1 and calculus 2 imo.
Idk about american system, maybe skip some basic sum series.

From what i hear calculus 3 isn't particularly hard, but without the entire calculus one and solid understanding of multivatiable calculus + integrals you are fucked

High school calculus is bullshit compared to college, you need at least a month to learn what you didn't

You're fine honestly

Oh man, thats the same calculus book I had in college. Just seeing that picture again brings back horrific memories.

>What concepts should I brush up on so I'm ready to take Calc 3?
>Brush up
You haven't learned what's required to take calculus 3. Be ready to learn derivatives + integrals all by yourself, including rotating solids and practical problems.

That or step back and take Calculus 1.

Learn integrals and derivatives. Thats pretty much all you will need for calc 3

T. College male taking calc 3 currently

i was in the same boat, as long as you remember how to take an intergral and a derivative you should be good to go
