@@countdracula2836 It's not bad to ask for questions. Why would they be called "teachers" if they don't help the students learn. We go to school to learn anyway, not to judge.
It's so sad watching how little your students appreciate you. If you were my math teacher, I'd leave my phone at home when I came to your class. They have no idea how lucky they are to have a teacher who actually knows how to teach
Sad to see how little you appreciate your education. This teacher is like any other ive had i dont know about you so stop bitching about how bad you have it and leave your phone at home with the teacher you have now.
@@mr.thundercock4961 Some teachers quite literally don’t want to do their job. My math teacher for the past two years would shove us in one of the classrooms in the school library and just leave us without giving work (so she could go drink coffee with her teacher friends). When we would go to ask her what we are meant to do or to ask for help because no one knew what we were doing she would tell us that we need to problem solve and ask our peers or just straight up ignore us. Then when 75% of the class failed she would lecture us on effective studying and how we were “slacking off”. So you see, I would be thoroughly grateful to have a teacher who actually taught.
If this video or many others was helpful, please consider letting me know with a "Super Thanks" above ⬆. I am able to read and respond to all my messages and thank you so much for your support
Everyone is talking about how they learned this in 10 minutes but took them 2 weeks to learn in school, but nobody realizes that this is a school lesson.
Your students are very lucky. Our notes when we went over this didn’t even have the vertex formula on them the teacher just kinda mentioned it once and expected everyone to memorize it. I could probably dig up the notes and take a picture for proof.
@@elfttt8493 No school's ever right. Kids who fight back will end up in the office for assault or something like it. Counselors aren't helpful either. My suicidal friend got better because of his parents, not the counselor. Don't even get me started on the nurse and teachers
I really appreciate your videos because I have a hard time understanding my math teacher. Which caused me to feel stuck and struggled to understand the material. I love how you mention so much information in just a very short video. You are a life saver! Thank you!
you are a million times better than my math teacher. i would literally fly to where you teach and just have you lecture me for a few minutes daily. i understood it better than i ever did and i thank you for that.
I wish my math teacher was like you! 😭 He's the kind that can't dumb it down and expects us either to figure it out or just already know this stuff 😭😭😭 your a life saver!!!
Thank you so much! My math teacher is great, but he tends to overcomplicate things sometimes. This really helped clear it up. Wish me luck for the test tomorrow!
For nearly a week now I’ve been completely out of sync with my advanced algebra 1 class, but you managed to catch me right up to speed and in such a short time. Thank you so much for what you do
Hey Mr. McLogan, I know this video is ten years old but I just gotta thank you for making content like this. I don’t always understand math because my teacher isn’t very ensnaring and has no energy, but I really got the hang of it. Thanks
rn I’m in quarantine and I have to get packets for my school and I missed out on a week of work so I’m getting confused with these numbers. You’re always the one I go to for these types of things, ty for helping me!
I thank you, sir, for teaching this again. I am a grade 11 student/senior high school student, and i forgot these topics. Teachers make me feel dumb, like they say "I dont need to tell you this, it's not my problem. You should already know by now what is this." This may raise my self esteem. Thanks for this video.

Similarly learning abilities and styles also vary from student to student. Keeping in view this theory one on one class with student can help student more in learning than a combined class.Moreover, it would be easy for a teacher to assess student by pointing out weakness and work on them to enhance learning and performing best in the exams etc. This can only be made possible if a teacher is certified pedagogist and he/she excelled in subject/course teaching content with enough teaching experience.

just got a new long term sub that actually knows math, but she started off quadratics with graphing things like y=x^2 and functions that don't have whole x values. Most people in the class have never even heard of a parabola either.

This may be an older video but it was a huge help! I’m a freshman in college and embarrassingly needed googles help with this again - but you’re the first person who’s explained it in a way that made the concept stick!
I hate to say this but if a student asks "how did you get 2a" the answer was "Because that's the formula for... That was in your last class notes", is a terrible response... Obviously the student didn't get the importance of that formula and it should've been reiterated... This is definitely why I never got math either... teachers who dismiss a student's honest question with a shitty attitude. #BadFormSir
There is no explanation for a formula...him saying that its the formula is the best he can say and he would obviously become frustrated if it had been explained previously and no attention was paid to it
if i studied this topic in the class its sooo hard... but if i watched this video i know this topic is very easy... Thank you very much sir. This video is very useful......
I'm taking a BSEd course major in mathematics, but we gained little knowledge during online class and this video helped me to go through the lessons I don't understand. Thank you so much!

when a>0 ( a is greater than 0 ) your graph is going to open "up"

3:13 NOW WE'LL FIND our tables of value AFTER determining if our graph will open "up" or "down" .( ask , how is our "x" value of our vertex related to our axis of symmetry ? 3:57 )
our vertex HAS TO RUN THROUGH our axis of symmetry , and since we determined **by using the formula ** ( x = - b / 2a ) that our "axis of symmetry" is 4 , THEN our x value of our vertex IS ALSO 4 .
4:17 how to determine y value ( really your * f(x) value ** ) of the vertex by plugging your x value of your vertex in your function ) so you can "graph " the vertex .
5:13 determine atleast "two points " to the left and "two points to the right of your "graphed vertex ) by table of values
6:36 using shortcut of "symmetry " by finding two points to the left or right and "since" its symmetrical you can jus "mirror your three "graphed" points you have , to finish graphing ...
