My exam is in a bit under 12 hours. Thanks for making this video! I definitely should have gone over things earlier, but this recap should be enough to land me a good score.
@@milms3956Sorry, but I just now finished, so you’re already taking it I assume. It was relatively easy. It’s the same as every past AP test, so if you compré this one to 2023’s test, it’s the same format. I can’t really say anything specific, sorry.
the area slices in polar @2:58 are actually because of sectors of a circle, not triangle. You can't get 1/2 r^2 dtheta from the triangle formula, but you can get it from sector of a circle formula. area of circle is pir^2 but we only have (dtheta/[2pi]) fraction of the circle, so the area of our slice is 1/2 r^2 dtheta
You can get it both ways, but I don't think it really matters. It is an infinitesimal piece which isn't really either part of a circle or a triangle. It's only "approximately" either one of those things.
@@AllenTsaoSTEMCoach the point is you cannot get 1/2 r^2 from the triangle way. area of a triangle is 1/2 b*h. The height of your infinitesimal piece is r, but the base doesn't really work because it is a curved base. It's similar to why the arc length formula is integrating along the line and why the surface area formula includes arc length in its formula. Doesn't really matter cuz most high school students don't care and the triangle thing is a common misunderstanding.
@user-ll1ow4xf8n it's not necessarily a curved base. What if it's a straight line like r = 1/cos(theta)? Can we not use the equation for area anymore? You're approximating it as a portion of a curved path. It's still an approximation where the error goes to 0 as the slice shrinks to 0. But it's not necessarily curved as part of a circle
happy to see comments showing im not the only one fried for the exam tomorrow
😢😢
MY CALCULATOR DIED ITS ACTUALLY SO OVER
@@cynarancia🤯 you’re done…
Ok, time to start studying.

AP BC test coming soon, thank you so much. I think this is a very nice overview of the BC specific topics.
good luck everyone tomorrow!

I feel like I nailed all the multiple choice and even the frqs tysm
It may be over for all of us. Nevertheless, godspeed, soldiers.
my exam is tomorrow thanks for the video!!
same lol
@@7upcola686 SAME
Samee
WE NEED PHYSICS C MECHANICS RECAP PLEASEEE!!!!!!
I'll do my best to get one done
I second this!
Do electricity and magnetism too!!!
Don't worry guys if you get above a 40 on the exam you can get at least a 3. Good luck everyone 🙏
my teacher didn't even teach us parametrics 💀
😱😱 good luck!!!
please have my kids
I’m watching this 2 hours before the exam 🤲
How was it I take it soon 😭

In calc ab rn, this makes no sense😂. Will watch this next year.
i havent started studying yet :(
Exam tmrw am I cooked 😭🙏💀
im so cooked
BRO😂😭☠️☠️😭
@@yna418 😭
Same
LOCK IN
yeah it’s so over for me 😭🙏
im cooked dont worry ill drag down the curve ✊✊
I am so stressed for the AP test tomorrow…. Anyone else??
Same brother, just know, it is what it is.
exam in an hour. i don't know what half this stuff is. am I cooked??
My exam is in 40 minutes we got this! (I’m screwed)
My test is in 6 hours i love u dude id take bullets for you
watching this 30 mins before my exam😝
10pm night before the exam i think i got this
Doesn’t a particle speed up if the acceleration is positive? Kinda confused between the two concepts
So if the velocity is negative, then it goes faster by accelerating in the negative direction (makes the velocity more negative).
Good luck peoples! We ball
Takin the late exam so I gotta lock in 😂
chat im cooked for tommorrow
lock in guys
Yeah this helped but I got cooked anyway
I think ima get 1st place
i'm cooked but I may be a bit less cooked thanks to to you
You are amazing!!!!
was EZ
I actually love you much for making this video. Thank you!!!
I'm so cooked
my exam is in an hour
thank you bby
so glad i just took calc 1 and calc 2 during community college.
Thank you so, sooo much!
its over bros
Taking in 30 minutes 🙏 Gl to myself
HELEPPEP GOOD LUCKK (give me the answers 😭😭😭 joking btw LMAO)
I’m cooked in 20 min
Hahahahahahahahhaa
