Key Features of Function (Part 2) | Algebra
Просмотров 9710 месяцев назад
In Part 2, I explain the key features of function, domain and range, max and min, increasing and decreasing interval. After watching Part 1 and Part 2, you should have a basic idea about function. In the end, I give a brief introduction to all different types of functions that you learn in high school Math.
What is a Function Exactly? (Part 1) - Algebra
Просмотров 23010 месяцев назад
In this video, I explain what a function is in simple words. Knowing the definition of function is critical in learning Algebra. I also explain the difference between function and equation, how to verify if a graph is a function, and 4 different ways to represent a function. In Part 2, I'll go over more details about a function, such as domain, range, increasing/decreasing, x and y intercepts, ...

Cram AP Chem Unit 1: Atomic Structures and Properties
Guys, anyone has timestamps??
are there any cram ap chem unit 5?
Is this international AP chem or America AP chem
It's just AP Chem. International and US use the same syllabus. The only difference is test paper. But they basically test you on the same materials.
@@academic-coach-youhyun thanks
Morllax coulloruas Sufi .
Kwatt 83.463 does it round up to 84 . Ver. 200min
1:05:20 why do we assume final velocity to be zero?
Hello! Will you be covering other units like Energy, Waves and Circuits? (I am aware that you also have a Dynamics video.) I really appreciate these videos, they are incredibly helpful. Thank you!
I'm not cramming, but i'm going from teaching biology to teaching AP physics lol. Thanks for these videos!!!
legend, thanks
Your explanation is great. I understood this finally
videos are very helpful and I am going to have ap physics 1 in one week, can you please make one for the energy unit? Thank you very much!
Do you have the energy cram pls share
TIME TO GET THAT 5 🔥
thanks for saving me from ap chem in around a day
THANK YOU!
Video actually starts at 6:17 👍
Hi how did u know to put h20 and NaF in the products? In 14:07
This context is a acid-base reaction, so the proton from HF (H+) is donated to the OH molecule. This results in H2O being formed and a spectator molecule that results from the leftover atoms (Na and F -> NaF).
It should be noted however, that she got it wrong in this case because HF is a weak acid and does not dissociate and therefore HF should stay together in the final reaction, netting HF + OH- --> F-+ H2O
At 1:18:47, for part e), does it matter if you label CO + 2H2 as the products, rather than CH3OH? I found this question on CollegeBoard and found that the scoring guidelines said to do it the other way.
I went ahead and looked at the actual question. The prompt provides the reaction as CH3OH -> CO + 2H2.
hello! I was wondering if we had to memorize names of the chemists and what their significance was for the AP exam?
No you don’t have to
At 1:18:09, how do you determine which one is the product or reactant? And why did you didn't use the number of moles given in the diagram, like 6H2? I thought we need to follow the diagram. Please explain!!
Forget about my first question, you answer in the video.lol. Please explain my second question!
In this context she is balancing the chemical formula. There are 4 H's present in the product side, so 4 H's need to be on the reactant side to balance the mass
this is the best ap chem review. how did i not find this before
This is the absolute best ap chem review I have come across. You are amazing and I am extremely grateful for you. Thank you so much!!! <3
thank you for your patience and effort. I really appreciate your videos:D and they are very helpful too!!!
SUCH A GOOD VIDEO!!!!!!!! I LOVE YOU ONNI!!!!!!!
How is the Mg2+ and Ca2+ have the most charge, I thought +2 means it lost 2 charges which would make it weaker, Thank You. 21:11
According to Coulomb’s Law the bigger the charge the bigger the attraction
My logic is that it doesn't matter whether or not it's positive 2 or negative 2, as the guy above me said, as long as the charge is big it will have a higher attraction rate, correct me if I'm wrong though;;
This context is in regards to the ion-dipole attraction between a Cation and a H2O molecule. The more positive a charge on the cation, the stronger the attraction between the negative dipole on the Oxygen in the water molecule and the Cation as given by Coulombs Law.
한국인이신가요?
In the last question, since the solution is diluted doesn't that mean that it would allow more light to pass through? Since there are droplets of distilled water? So the measured asborbance would be too high than in reality?
I don't think the frosted sides mean dilution but that the light passing through gets absorbed by the frosted side AND the FeSCN making the results not accurate since light is getting absorbed by another substance as well so absorbance would be higher
no, absorbance is proportional to concentration according to Beer’s Law
plssss can you add a a physics c mechanics portion
For most of the concepts you can still watch AP Physics 1 series. I will make Physics C problem solving videos if I have extra time.
Hi!! Your explanations are so clear and helpfullll please do some of the other units before the exam!
Thank you! I will post more. Please share it with your friends and classmates who might need it.
wuaww your explanation is really clear and helpful.❤ Please do other topics as well🥹🥹
Thank you for positive feedback. I’ll complete the rest of the units.
@@academic-coach-youhyun ❤️🔥
1:21:25 isnt this a trigonal pyramid because one of the bond pairs has been replaced with a lone pair, so the angle should be 107 degrees and not 109.5
When I pass the AP exam I’ll be thinking about you ma’am😭🙏❤
I answered all the MCQs and FAQs correctly! I am so ready for the AP. Thank you.
hi! did you watch all her videos to study before doing this review video?
@@steph-mj8dx this is what I'll be doing starting today haha, best of luck to you too :-)
@@user-xe7dx8un3i goodluck today 😔! personally, i am so cooked
1:11:50 You wrote Ag + Sr2+ => Ag+ + Sr, it should be 2Ag + Sr2+ => 2Ag+ + Sr (I think) (because the equation needs to be balanced)
1:09:23 You keep on saying “serenium” and then you write Sr for the reaction. I think you mean selenium:Se or strontium:Sr.
You're right. Thank you for correcting it!
I should’ve watched this before I took my unit 2 exam but I’m looking up for the AP exam after this 😭💪
@academic-coach-youhyun What is the difference between ICE, ICF, and IMF tables??? I am on a tight line for the AP. By the way, I really appreciate your videos.
I(initial) C(change) E(equilibrium) is used when the reaction eventually reaches equilibrium. ICF(final) is used when the reaction goes to completion. To be honest, as for calculation you can use ICF instead of ICE. This is just an easy way for doing math and it's not some Chemistry concept. You won't get points off in the AP exam for using these two interchangeably.
I've not heard of IMF though.
Thank you ❤
hello, where did or where could you find AP questions for this, besides the past AP frqs
Icf table? What is that?
Initial, change, final
What is a ICE 🧊🧪 chem table? I don’t get it. Please explain.
I stands for initial values, C for change, and E for equilibrium
Hello thanks for the video, but why do you not include Yo initial at 25.33?
don't we also need to plug the height of the building at 25.33 as this would be the value for Y initial?
hi!! this video helped me so much to prepare for the beginning of AP chem this year, but now the AP exam is coming up. can you make for videos for after unit 4? thank you!
its in the playlist
Worth it video 😊Thank you Midterm in 3 days..Wish me luck☺️
Deserves millions of views tbh
Thanks for support!
I cant hear anything huhuhuhu
