YOURE SUCH A GREAT HELP MRS. KOSH!!! I LOVE THESE VIDEOS, YOURE SAVING MY LIFE LOL :)
Fantastic!!
this is still valid! great explanation !!!
Awesome!! I'm glad it's still helpful!
I did this question: a ball dropped from a height of 10 metres . Each time it strikes the ground it bounces 3/4 the previous height, calculate the total distance travelled by the ball before it stops.....i tried it and got 70 metres but the answer sheet says 90, I don't know if I'm wrong
I got 70, also. Was that one of my worksheets?
The total distance the ball travels down will be 40 meters. The total distance the ball travels up will be 30 meters.
Mrs Kosh you're off beat in the song, can we make a remake? -Shawroj K, Bhargav N, Pranav S
Yes. You make a video, and I’ll upload it.
tysm i have been looking for such a video for a month
Awesome! Do I have any other topics you need?
I understand it now
I understand it now
Yay!!!
Very good, not a lot of people cover specific topics especially in the title.
Glad this was helpful!
hey! another fellow appc teacher here. i have some of bryan passwater's resources but not all of them, can't download from the facebook for some reason. could you share your email so i could reach out to you? Thanks!
I don't want to list it online, but I teach in Coppell. Can you see if google will help you find it?
I think your explanation is in the right direction! It might be helpful to consider showing how for: y = b^x log(y) = x*log(b) I think this makes it more clear how a logarithmic transformation makes the exponential function a linear function and would make plotting it more understandable.
Thanks! My understanding definitely improved as I kept going. My best video on this topic was the 4th: th-cam.com/video/bgQyXJ8f6PQ/w-d-xo.htmlsi=HRVQ5-JqZtHRsexf
I really needed this and this was very helpful .Thank you.
You're welcome! Stick around... I'm sure I have other topics that will be helpful. :-)
Good explanation.
thank u for teaching me more than my own teacher🙏
Yikes! Happy to help. :-)
Currently in algebra 1 watching this, it makes my brain hurt
Hang in there!! Math builds. I'm not sure I have too many Algebra 1 videos - I've have not taught Alg 1 since TH-cam was invented, haha! But... I can try to make a video (or two) if you have a specific question.
@@karieekosh7964 okay! I can make a suggestion, you could do like transformations of functions.
Search my site for transformations. I bet I have a bunch of videos already.
I’m cooked
No!! You will cook.
i have no idea who you are but you have saved my life. I hope you keep posting these because my teacher makes us take tests based on bryan passwater's notes, and she doesn't give us them! This is super helpful and I hope you continue.
Glad it's been helpful! Share my channel with your friends! I do plan to continue making videos. If I don't make a video on a topic this year, check my playlists. I might think that last year's video is good enough.
I like ur solving but those slit mistake reduce quality for someone to consume it.😮
Sorry. The video is six years old. You could search my channel and see if I have videos on that topic that I made more recently. I've definitely gotten better over the years.
Where can I get this worksheet?
Mr. Passwater has made his resources available to many (maybe all??) AP PreCal teachers. Are you a student, teacher, or parent?
@@karieekosh7964 I'm a student
@@karieekosh7964 So this worksheet is not on the AP collegeboard website
I don't think so. You can ask your PreCal teacher if he or she has joined the Facebook group for AP PreCal teachers. There's access to Mr. Passwater's resources through that group.
@@karieekosh7964 alright thank you !
In 12 bounces, there are 13 downwards and 12 upwards
this video saved my life thank you so much
Fantastic, haha!! Glad to hear it!
this was good ty
But the last inverse graph at 5:57 is wrong though.
@@aimanfatima8316 Oh. Sorry! I tell my students that "I'm good, but I'm not perfect."
Hey Ms Kosh!! I was a little confused. Given a meromorphic function 𝑓(𝑧) f(z) with a simple pole at z=a, find the residue of f(z) at 𝑧=𝑎. How could I apply these notes to solve that.
Good question! To be honest, I have no idea! If I studied meromorphic functions, it's been a few decades... Good luck to you!!
13:59 ✨-924✨
Awesome!! I found the value when I taught this to my students, but I wasn't so inspired when making my video, haha! Thanks for giving me the number!
Thank you so much! The way you explain it is much easier to understand than my teacher. Thanks to your videos I got a 91 on my first test :D
Fantastic!! Stick around and share my channel. I'll make videos all year long. :-)
I understood this very well. I am just a bit confused on how to apply this for some other questions. For example, I have this problem that has me prove a pattern in the lucas sequence with the remaider from dividing Ln by three. Would I need to make a formula, use the sequence I already have from the lucas funciton and just replace n with k+1?
Good question! I wasn't familiar with the lucas sequence - a quick google search showed me that it's very similar to Fibonacci's sequence. I'm not sure if I've done any induction proofs with Fibonacci, but I imagine you'd need to use the explicit definition of the nth term of the sequence. It's a bit messy - all I remember is that it has a couple root 5's. Hope that helps... Good luck!
thank you so much, this helped my dilemma
Glad to hear it!
thank you so much
You're welcome!
Hello Mrs. Kosh. I hope you’re enjoying (or enjoyed) this summer break. Thank you for so much of your videos which have helped me during the school year. I wanted to ask if Bryan Passwater also creates AP Calculus AB content. I’m going to take it this year (this Friday school starts 😮😅). I like his work a lot, and if you’d be able to go through it I’d appreciate it a lot. Or if you can go through your own AP Calc content it’d be fantastic. Thank you so much ❤
Thanks for your kind words!! Glad I was able to help. Unfortunately, I haven't taught Calculus in 18 years, and don't have enough time this year to do it justice. My colleague - Ian VanderSchee - has great videos and he teaches Calculus. Try searching for his name.
@@karieekosh7964 Thank you very much. I’ll make sure to check him out. Hope you have a nice day 😁😎
Thanks! His channel is Blue Shirt Khaki Pants. Enjoy!
For example 3a, wouldn’t it be quadratic since 4 + 5 would equal 9 and that would make the difference between 5 and 3, 2, which would mean that it’s the same as the difference between 3 and 1? I got a bit confused on this part so I wanted to make sure that I was getting the right info. Your videos are really helping me in my class :)!
Sorry!! Looks like you're right and I forgot how to add and subtract. Good catch!!

Welcome!
@@karieekosh7964 is this course for college sat ?
I teach in a high school. Our AP exam may give college credit, but it depends on the college and the field of study. We're a new program.
Thank you so much ma'am, my precalc class is starting to get confusing. This helps
Awesome!! Subscribe and stick around! I have lots of videos from last year and intend to make many more this year.
I also thought 11.4, but if the max is increasing after each iteration then the max is more likely 12.186 no?
it has been 4 years and still no comments
Funny!! Did you find the video helpful?
@@karieekosh7964Yupp! It was very helpful indeed. Thank you 😃
@@karieekosh7964(sorry for bad english as its not my first language)
okayyy
Hi this is very helpful can you provide the links for the handouts?
Glad it's helpful! I added the link to the description of the video.
Good teacher 👍
Thank you! 😃
Is this legal? I don't actually care, I'm just curious
I hope so! Not gonna lie... I'm really confused about "secure" vs. not secure. I've tried to do things correctly, but I'm new to the AP world...
I do believe it is as they have already publicly displayed the questions on their website
can you tell me where you got the notes from Vikki Carter - can I purchase them somewhere?
I was given access to her work when I went to an APSI. She may have them posted in the Facebook group for PreCal teachers. Are you in that group?
The student was Gauss!! Awesome video!
Haha! Thanks! (Did I remember it correctly in the video? Sometimes I do... sometimes I don't...)
So the AP Exam was yesterday. Drum roll.... I did amazing! One reason I did so well yesterday and felt so confident was because of you. Although I wasn't able to finish all of the Unit 3 videos, I found every minute of this entire playlist extremely helpful - thank you so much! Hopefully when I'm in AP Calculus next year you will be able to publish similar review like this playlist! Happy teaching and learning :)
So glad it went well for you!! Share my PreCal videos with your friends. :-)
Wouldn't drawing secant lines through the points also serve as a way to find average rates of change? For example, it is a steeper and negative slope from D to A, hence it would be those points...
I'm still not 100% comfortable with average rate of change in the polar world... I'll have to talk to my colleagues who teach BC Calculus. My sense is that things are different in the polar world - take the points (3, pi/2) and (3, 3pi/2). You get zero when you subtract the "r" values, but those two coordinates would be on the same vertical line.

Hey these videos are great! Can you do a similar full length practice test video?
Not sure if I'm allowed to say this, but there is a guy by "Math Teacher GOAT" who has uploaded 2 full practices with explanations. Also, a bunch of other people like RH Mathematics.
I won't have a chance before tomorrow's exam, but if you have something you want to send my way, I'll see when I can get to it.
Hi there, is there any way I can gain access to these FRQ papers online from Mr. Bryan Passwater?
He's made his resources available to teachers in a Facebook group. I'm not comfortable sharing the pdfs beyond my classroom.
for question 14, there might have been a typo or an error if you will in part b, where it would be true if Beta was positive, and the same for answer choice d with alpha because negative instead of positive
Yeah. You're right. Either of those changes would work.
@@karieekosh7964 yup. This review is very helpful, taking the exam on Monday your a great help 👍
Glad I could help! Good luck to you!
Greetings and salutations! This is semi-unrelated, but wanted to ask anyways. Do you know if college board gives a formula sheet for the test? There are so many things to memorize, I'm going crazy lol. Also wanted to know if these questions accurately reflect the test. I am taking the exam, but have no teacher, so I am kind of lost searching online for accurate mocks (that dont require a teacher account). Anyways, thanks for these videos! Your explanations help a lot (even in this monster of a question!).
Glad its been helpful! No. You won't get a formula chart. We've done the best we can to create problems that we THINK will be similar to the exam. We haven't seen an actual exam, so... no telling!
Hey is there any way you can post this unit 3 packet please. Our teacher gave up unit 1, unit2, and part of unit 3 but we only have 50 questions from unit 3. PLEASE!
Ask your teacher again, sorry! Mr. Passwater's dropbox should have what you're looking for.
I think the next question, part C is typically “write a sin or cos equation” so I did. Am I correct? y=8cos(pi x/15)+120 Thanks for your work!
Looks great! Good work!
I am not taking AP Precalculus but this is very helpful. Thank you :D
Super!!
THABK YOUUU
