Pre-Calc

Check the /sci/ guide next time.

There is no subject called "pre-calculus." You should have a very good understanding of elementary algebra, trigonometry, and know your basic rules for dealing with functions.

Calculus is fairly easy. I'd say there's more online resources than one could count.

Thanks!

just watch the trig algebra and functions playlists on khan academy or something

May ask what of trig is needed for calc?
I like to think I have a strong understanding of algebra/algebraic functions, but have never taken a trig course I don't think I should dive into calc without it.

It's fundamental as a tool for solving integrals and doing multivariate calculus. Trigonometric forms pop up everywhere.
I was taught that if you can't derive all the most common trig identities from scratch, you don't know enough.

Bruh. Google it. Kahn academy is easily the best resource out there for basic precalc, and calc too.

Oops. Great minds think alike I guess.

Is Khan academy really a good source to learn enough about trig/pre-calc so I can pick up calc?

>>7771036
You need to know trig identities, how to manipulate trig functions, how to simplify them and how transformations of trig functions work.

So you really need to understand trig so when you start derivatives and integrals, you are comfortable with working them and understand whats happening. Especially with inverse functions of trig.

He's ok with trig, just spend like an hour memorizing a list of trig identities. Trying to derive sin(A+B)=sinAcosB+cosAsinB is sort of a waste of time, in my opinion.
He's good with the part of pre calc that isn't trig identities, though. Just make sure you do the exercises on there and whatever you can find online.
As for calc though, I would recommend against him because he doesn't define things well... at all. He doesn't even derive the fundamental theorem of calculus, he just states it and talks about it for 10 minutes

Also, if you really like watching an Indian guy draw out a single problem for 4 hours in 93 different colors, I'd 100% recommend him.

Thanks for all the help guys!

IIRC he has a separate video deriving the fundamental theorem of calculus.
