We’re having a quiz on substituting values with x in integrals, and we’ve been doing derivatives of e and ln the past two days.
Nice, derivatives/integrals are so much fun! My class just finished all the AB content 
It’s super interesting!
We’re doing Newton’s method and differentials. We haven’t learned integration yet, but I don’t think we’re behind because the schedule is strictly set to end a couple of weeks before the test…
I have a pretty crappy teacher this semester (I switched to the better one for next semester) so I have a D right now and understand like nothing. We just started integration and finals prep because the final might be like half of our grade and no be very long. I bought a review book that should come before finals to help review and hopefully bring my grade up to a C-.
Has anyone made like quizlet flashcards for stuff yet? I might try and make some to study the basics and formulas I can never remember.
My class is a little behind right now. We are finishing up related rates (I swear we have worked out like 100 of them) and all we have left is linearization and differentials. Then, onto integration. All I can say is I’ve been dreaming about derivatives.
My class is about to take its FIFTH test on derivatives :)) It’s finally the last one. I can’t wait for integration lol.
We’re about to test on integration rules and basic applications this friday! We start advanced applcations afterwards and will finish the curriculum by late February. My calc teacher is pregnant and due in March, so we will have to review on our own!
I’ve been self studying using my school books (I’m an international student) but I think now is the time to get AP-centric books.
What books are you guys using? I’m thinking of getting PR, not only for Calculus BC but also Physics C and Chemistry. I’ve read that PR is great for the Sciences but Barron’s is better for Calculus.
@mundanewarrior, I’m using Barron’s for AP Calc
@Mathophile26 How is it so far? Would you recommend it?
@mundanewarrior I have Barron’s and I recommend it! It is divided up into sections really well. It also has so many example problems with eh explanations and has the rules listed out conveniently. I use it often and it helps a lot!
My class has a test tomorrow over integration… specifically the first and second fundamental theorem of calculus and everything that relates to those. Everyone in class is still mostly confused lol. My teacher is making it a partner test too.
And what would be your calculator recommendation?
I can get the used versions pretty cheap. The TI-83 Plus is $37 and TI-84 Plus SE is $60. I can’t decide between the two. They both look similar.
Why? I thought it was pretty easy. Looks like you haven’t gotten to the more difficult part yet: Techniques of integration. It gets quite complicated without a graphing calculator (which is not allowed in my school).
Okay, my dad wants me to buy a new calculator, because used ones don’t come with warranty.
The TI Nspire CX (non CAS), TI-84 Plus and TI-84 Plus CE all cost the same here (~$140).
Is it worth spending the extra bucks to get an Nspire? I’ll be majoring in Computer Science. I read somewhere that you don’t need anything past a TI-84 Plus in college.
@mundanewarrior In my opinion it’s better to get the TI-84 Plus (CE or not CE, it doesn’t matter). The Nspire has some commands and buttons that differ from a normal calculator that honestly confuse me. I’ve been using my trusty TI-84 Plus for years and it has served me well. My friend who has the Nspire constantly has to go to our math teacher to figure out how to do certain things.
@Shanban1607 “For years” you say? So I’ll be fine with getting a used one? The thing is durable, right?
Figuring out things is not a problem because I’m someone who reads the manual cover to cover. I just don’t think the $80 price difference is worth it.
I haven’t yet looked at the actual questions that are asked on BC Calc. But I saw a couple of videos on Khan Academy, and they used TI-83 Plus, so I guess I’ll be fine with TI-84 Plus.
But then I also stumbled across the Casio fx-9750GII ($55) and fx-9860GII ($90) that are cheaper and supposedly easier to use.
Now I’m even more confused.
Guys we are just finishing up related rates. We haven’t even started derivative applications, not to even talk about integration. I think I’m going to go solo.
@mundanewarrior Oh yeah, the TI-84 is very durable, I got mine used and it’s worked perfectly.
I don’t particularly like Casio’s, but mainly just because their commands are a bit different than TI’s calculators and I’m used to my calculator. But if it’s cheaper and has some good reviews, I’d say that one is great too
Okay, that’s great. I ordered the used TI-84+ for $50.
Now just to decide between Barron’s and PR.
