I appreciate that you put the problem in the thumbnail so I know what I am getting into, it makes things a lot easier so I don't have to jump from video to video.
you are very welcome! It took awhile but thought if I was a student would not want to waste time learning about a problem I already know or not what I am looking for
Thank you so much, I missed a week of school and my teacher gave me the notes but he skips steps (it's an honors class) and I couldn't figure it out. I think every teacher should record their lessons like that it would help so much. Thanks again!
@@AmenaYasserAbdElnabyEbrahimGoh because the x is squared using the formula (x-h)^2 it shows a vertical graph but if the y^2 we use (y-k)^2 which opens horizontally.
Thanks for the amazing video. You've cleared so much confusion I had over these, especially since the Common Core textbook just gives me a chart without showing me how to do problems like these step-by-step. You are an extraordinary teacher, and please keep posting more videos!
These helps me a lot !! I finally able to graph my parabola and learn all the things when in fact what i am ask to find is only the vertex, focal distance,and the opening. 💖
This concept is super easy when everyone instructs it in the normal format, my quiz has it in a format that the lesson plan does not even explain it in.
I don't know if you will respond to this but I'll still try my shot How do we find P if only the center/vertex is given and the parabola opens to the left?
I've been trying your method of adding P to h or K to find the focus, and it it just not working for any of the problems I'm doing. I tried it on the problem, 1/2x^2+6x-y+16=0. Could you help me out? Thanks!
I don't know if you'll respond, but I have an upcoming test. I was able to easily follow what you were doing, but I didn't understand how you knew the equation had a vertical transverse axis.
When you have the form as y = x^2, then it is a vertical parabola. When you have the form x = y^2, then it is a horizontal parabola. Opening up, will be x^2. Opening down, will be -x^2. And opening right will be y^2, and similarly for opening left, which is -y^2.
I go to Mandarin high school and I’m pre cal as a sophmore I wish I had you I know you used to teach here so I’m sad I missed out I do not like my current teacher in terms of teach ability
Why can't our math teacher teach like you..., all she does is give us papers and starts solving problems like there's no tomorrow, some teachers seriously need to be replaced!
I think the formula for focus and directrix are not accurate. When the p becomes negative, the formula for focus is (h), (k-p) while for directrix is y= (k+p)
Those ppl laughing at the beginning need to appreciate how good of a math teacher they have
Yes
yea we all know you cant make a single noise if u have a good teacher
I know! It’s like with Walter White in the pilot episode.
happy to help you understand
thanks!

you are very correct I hope that more teachers follow this because then whatever is specific to your class you can follow
I freaking hate honors classes they explain nothing like what then they give u a test every 2 seconds
When I did the problem I got (x+6)62 = 2(y+2) I will be happy to make a video as I need more examples in my library for these types of problems
how did we know that the parabola would be vertical?

Thank you for sharing this, I have a math final tomorrow and I needed help on finding the directix with a given vertex and equation.
I hope you did well on your final 5 years ago. I have a pre calc final tomorrow lol. Trying to maintain my A.
that is very possible, I have videos teaching it a couple different ways as well. Hope this way makes sense

really appreciate that Justin, I have no plans of stopping
Your students are very lucky to have a prof. like you. Cuz Everytime I don't understand the lesson, I'll directly search for your videos.
bruh i wish you were my precal teacher during quarantine
I have my Calc II final tomorrow. These videos have really helped me!! 🙌
You got this!
Pushing me to reach my potential led me to dream big and do extraordinary things. Thank you my teacher!🙏🙏🙏🙏🙏🙏🙏🙏🙏
Thank You!!! You have no idea how much I appreciate this video.
Mr. McLogan you are a lifesaver!
THANK YOU SO MUCH YOU EXPLAINED IT BETTER THAN MY PROFESSOR!!!
you are very welcome! happy to help
Man this video of yours is the best! Easy to understand Thank you for this!
Holy crap, you are astounding! Thank you!
You're the man, thank you for putting it so simply.
this was very helpful, i was struggling to figure out what directrix and focus was so this helped a lot
Thank you so much sir
Love from India 🇮🇳🇮🇳
Thanks, i missed a class of trigonometry, this helped me
Thank you so much, you got straight to the point without confusing us. Now I won’t fail math

you really helped a lot sir, thanks!
Thank you soooo much😭😭😭 this video helped me a lot
THANK YOU SO MUCH FOR THIS!!! I know I comment a lot on your videos.. but I cant express my thanks enough! THANK YOU!
you are very welcome Salem! happy to be able to help!
thank you so much, this wasnt taught by my pre cal teacher shs stem
bro is smart asf he might not make much as a teacher but im sure he makes a lot off these videos W hustle
You are a better teacher than mine. I never understood this but now i do. Im so happy!! Thank you ❤️
awesome! happy to be able to help you out Esha
Perfecttt, way better than my professor. Very clear and thorough! Good job. You get a cookie
haha thanks!
Love from india sir🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏🙏❤️❤️❤️❤️❤️❤️
This guy is literally the reason why I've passed geometry and Algebra II.
cheers to you Zain, keep working hard and happy to be there for . you
This was a huge lifesaver. Thanks!
you are very welcome!
Thank you so much, Sir, for sharing your knowledge to us.
You explain really well. Thumbs up.
chees thanks Momal
Would this be different for photons vs sound waves?
Wow you are so good at explaining
just happy to be able to help
big help in our society
Wow great video
thanks
I love how he is continuously giving weird looks to the students while teaching the lesson and always making sure they are still paying attention 🤣
Thanks so much this is great!
amazing lesson thank you! I can tell you really love to teach
happy to help, yes still enjoy my day job
thanks sir too much helpful .
from India
new concept for me
you are very welcome!
Thanks a lot sir. Btw how to find length of latus rectum?
4p If I remember correctly!
is it the same if the equation is opposite like side ward equation
You’re a blessing
thanks! we learned it differently, though... I think...
thank you so much for this.. all I have to do is look at the board because everything is right there. thank you for doing that.😊😊😊
you are very welcome!
Wow! This is so simple I never knew that! Thank you so so much!
you are very welcome!
At 0:45, can someone please tell me how is the center ( -3,1 )
This was really helpful thank you
still watching ur videos in 2020
hello sir...how do i know its vertical or horizontal focus?
if the x is squared it is vertical like a quadratic, if y then horizontal
Bro you don't even realize how much you save high school math students
Short and sweet.
go Jags! Duuuuuval
I don't know if you will respond to this but I'll still try my shot
How do we find P if only the center/vertex is given and the parabola opens to the left?
That is not enough information. You will need one more point unless it is assumed no dilation/stretch then p is 1/4
धन्यवाद गुरुजी!
I've been trying your method of adding P to h or K to find the focus, and it it just not working for any of the problems I'm doing. I tried it on the problem, 1/2x^2+6x-y+16=0. Could you help me out? Thanks!
I don't know if you'll respond, but I have an upcoming test. I was able to easily follow what you were doing, but I didn't understand how you knew the equation had a vertical transverse axis.
since x was squared I know the graph either opens up or down, if y was squared it would be horizontal
When you have the form as y = x^2, then it is a vertical parabola. When you have the form x = y^2, then it is a horizontal parabola. Opening up, will be x^2. Opening down, will be -x^2. And opening right will be y^2, and similarly for opening left, which is -y^2.
thank you so much!
you are very welcome! happy to help
I have a question!why is h,k is -3,1 not 3,-1?
Thanks Brian
you are very welcome!
How did you know sir that the focus
(h, K+p), between K and p is add?
same question 😥
thanks,🤩
Can u explain 1 doubt of mine
Your 10 years late hahaha
thanks sir ji nice vedio
happy to help
i wish you're my real life teacher
How do you know if a parabola is vertical or horizontal?
is it not a negative 4p instead of positive? because it opens downward
nvm i got it . thankyou verymuch sir
This guys the Johnny Sins of math
thank you sir ,i confused in this type question but I am clear
confused or clear?
@@brianmclogan He is saying that he was confused, but you cleared it for him
Hi, how do you know if a parabola opens vertically or horizontally?
from an equation? x^2 then vertically, y^2 then horizontally
Literally saving me in finals
hi sir may i ask why it turned out to be 3/2 I don't get it po , im slow in math 1- (-1/2)
what is the form of the parabula is it upward or downward?
in conic sections?
sir, if the parabola in form of
(y-h)^2=4p(x-k)
will directix be x=h-p
yes
How do you know its vertical or horizontal by just looking at the equation?
the equation has x^2 so its vertical but if it was y^2 then is horizontal.
Why you add the p on the k?, since it's horizontal shouldn't it be on the h?
no x is squared so it is a vertical parabola (quadratic equations)
Im a bit confused instead of (x-h)²=4p(y-k) why not(x-h)²=-4p(y-k)??
Thank you, this was helpful. My math book sucks...
sorry to hear, happy to help
I go to Mandarin high school and I’m pre cal as a sophmore I wish I had you I know you used to teach here so I’m sad I missed out I do not like my current teacher in terms of teach ability
Thank you so Muchhh
you are very welcome!
How is 1 - (-1/2) = 3/2
Minus a negative is adding a positive
Do parabola even have a centre
homie savin me on my calc exam tmr. 9 years later... lmao
that is really sad, sorry you have to go through an experience like that.Schools are bound to change
I am confused at 1:40. how is -2=4p?
I get it now
okay! let me know if there are any other parts
How about y²=16x
Why can't our math teacher teach like you..., all she does is give us papers and starts solving problems like there's no tomorrow, some teachers seriously need to be replaced!
why is it -3,1 ?
Excelente!!
thanks!
thx so much
you are very welcome!
gracias papa
I think the formula for focus and directrix are not accurate. When the p becomes negative, the formula for focus is (h), (k-p) while for directrix is y= (k+p)
1:17 🅿ushin 🅿
Again I am telling you. You are a good teacher!!!! But u get so confused while solving it and miss important things 😒
sometimes I confuse myself, yes
Brian McLogan who cares no one is perfect! You make everything easy to understand. You’re doing amazing thank you SO much!!!😊
I’m not sure why you adding 4p because there is no 4 you’re just making it up.
Can someone tell me why he put 4p???
It’s the formula
clear
