but how do you identify what numbers to choose from when making the equations and how do you learn the process of how to correctly make the actual equation itself
This has taught me more than my teacher in under 5 minutes

I completely agree XD I only needed this video because my teacher made it seem unnescessarily complex

Ture bro

This is amazing!! I have gotten so much help from the Biology and Maths content. ❤ Can’t wait to see how I do in my exam.
And how did you do??
@@ThijsSch Damn
I wish my math book was as neat as your videos. Great explanation and effort Cognito 👏
This channel is too underrated
This helped me a whole lot thanks ❤
Is there a video on Laws of Chemical Combination concerning Chemistry??
5:08 i was also taught that you can find the exact value (of the minimum point) by inputting the turning point’s (minimum point) x coordinate into the above table and run it through the same eq. After that you’ll receive a y which should be your exact answer.
Though, this is a symmetrical graph so that changes a lot of things, i havent learnt too much about non symmetrical graphs to figure the turning point’s y value
That's the same thing what I was going to comment
bruh I had no idea what to do maths today and now I like got every question right because of this video
Wonderful teacher
Thank you so much for your effort I love your videos they really help❤️
This was extremely helpful 👏 🙂
life saver, very imformative
This video is good, however there's just one thing I can't quite comprehend.
When you work out the "table" for example 3:12, you got 11 for -2. When I tried to work it out, I got -2. If you could help me, that'd be greatly appreciated. Thank you!
Hello, I'm not the best at maths but I'll try to help you. So the sum is y=x^2-3x+1. So lets work it out for -2. Basically, you substitute -2 in for all the x's. So the equation would look like this: (-2)^2-3(-2)+1. -2^2=4 -3*-2=6 and so you are left with 4+6+1 which equals 11. Hope that helps!!
@@lemondrizzle2355 Oh my god, Thank you so much! This helped alot.
wait how did you get y=5 ? 😭
because you substitute x being 4 into the quadratic equation:
y = x squared minus 3x + 1
This gives the answer y = 16 - 12 + 1
Which means y = 5 as final answer
Hi
I'm going to fail
No one notice that he tried his best to not breathe too loud?? But thanks man 🙏
?
Since the winter holidays I've put off all my homework till the last day, and now I'm having to recall everything before, this is so so helpful!!
Hey mabye do geography videos? A lot of geography is science, physical geography
no
No history >
Wow, you made this look so simple!
I generally never comment, but had to for this, to thank you! Thanks! Just subscribed!
pls make a video on functions and graphs of functions. i always prepare for tests from ur channel and i have a moq tmrw and couldnt find any videos on it :(
Watching this before mock exams😂
I've just started year 10 can you explain to me what you are tested on in mocks. I disabled my comment so just like the comment so I can see it
@@Aderin. mocks are basically just practice gcses.Most schools just use past papers so I would advise going onto a past paper website like physics and maths tutor, savemyexams or your exam board website and just looking through them to get an idea, and maybe practicing some of them.
awesome best teacher in life
I have my non caculator tommrow and I didnt even know where to begin for Qudratic graphs so thank you so much this video has now given me so much confdince walking in tommrow ❤❤❤
found it very useful was struggling on this for the past 1 week really helpful keep up this good work
Great to hear the video cleared things up for you 👍
Thankyou so much, much appreciated ❤️

Hello! Why did you find the values within the range - 2 and + 4 ?
🌻🌻🌻🌻🌻🌻🌻🌻🌻
My teacher from IITD took 2hrs to explain this now me here doing revision
Is there a limit to x value.why can't I put value out side - 3
Your a cool man cognito you help me so much in all subjects
I never thought I would completely figure out a topic on my exam (tomorrow) in 5 minutes
Please i need more tutorial 😊😊
thank you i learn so much on this vidoes
This guy is underated
I’m so grateful for your videos
man you are a miracle this was so helpful.🙂
THANK YOU IVE BEEN NEEDING THIS
thank u kind sir.

Simple and effective! Could you make a video on the inverse process? Once given a graph of a quadratic function, calculate the function. I cannot find anything simple enough to understand! :D

Hello, I would really appreciate it if you could answer this question quickly. how do you plot a curve if it doesn't give you the range from where to where to plot it for example the question just asks plot y=x^2+2x-5. how do I find out the range?
First find the x axis(or the x-axis crossing points) of the graphs by taking y=0. Than solving the equation....u may get two values of x and those are the x axis of the graph.
Than to find the y axis take x=0 and find the y intercept ( or the y-axis crossing points of the graph) and than to find the minimum or the maximum point of the graph...well convert that equation into it's square form.
After that draw a smooth graph following those points u got from the above steps and join them!!!
That's how u get to draw that graph without an range hope that helps ☺️
@@mantosh56 Oh right thank you sm
This really helped a lot, you are the only video i for curved graphs. You saved my math exam😭
I want to like this more than 10x... thank you very much 😊
Very helpful 😊 video thanks 👍
Can do how to sketch a graph?
Name the conditions for the graph to be considered sketched.
thanks brother this helps a lot!!, although I am from Igcse it still helps
bro thank you so much i was so confused 😄
dont think you`ve done a video on this but could you do loci and constructions
I really liked the video,thanks
Why did you choose -2 and 4
Thank you, this helped a lot!!
Great vids guys
Clearly explained
AMAZING
Thank you!!!
thanks!!
Thank you so much, seriously an amazing explanation. I wanted to know if this is some sort of platform you are using to create and work on these equations or it's an animation? If it's a platform can you please tell me it's name?
Hey, the videos are made using a mix of Adobe after effects, photoshop/procreate (iPad app), and Final Cut Pro :)
@@Cognitoedu Wow, that's a lot of work behind the scene. Thank you so much for putting this much effort for helping students in their studies. Wish this channel all the best! Thanks for the reply to.
Hi, could you make a video on function transformations? thanks. Your videos are so great btw
Hey cognito im kinda confused as to where you get the number range for x from 0:50
It says In the question that the values of x must be between -2 and 4
@@recklessrat613 it's seven months later and I figured It out like the next day
@@recklessrat613 I appreciate that you would reply tho
@@akgunrsorry
@@akgunrlol thank you boss
The first table of graph is wrong it should be y = 5, -2, -3, -4, -3, 0, 5 1:45
1^2-1(-1)-3=-1 not 0?
No
