Pre-Calculus - Conic Sections : CIRCLE

In this video you will learn:
A. Transforming General Form to Standard Form of a Circle
B. Transforming Standard Form to General Form of a Circle
C. Finding the Standard Form of a Circle Given the Radius and Center
D. How to Graph a circle in the Cartesian Plane

For the example (x+5)^2 +(y-1)^2=9
The General form must be x^2+y^2+10x-2y+17=0 then the F=17 😁

Thank you so much po, I think sa 22:20 po 15 should be 17 correct me if I'm wrong ❤ thank you ulit po

My school year hasn't started yet but this video is helping me so much. Thank you for providing this video for us STEM students. :)

[EthanGianKarlVTraya]

i saw one mistake probably that solving part like 26-9= 15 is that supposed to be 17? did y’all agree?

[_larah]

26-9 = 17

Gsgi kala ko Mali akin e HAHAH, magwawala sana Ako :>

Hello sir thank you for this video its very informative. But may I correct you sir regarding the correct value of F should be 17 po not 15🤗

[deandamian]

thank you so much sir for explaining things in a way a student can understand. i will share ur channel to my classmates! im hoping more students can discover your channel🥰

[chaddernesto]

God bless u sir for helping a student like me especially I'm not good at math tapos STEM pa kukunin ko BWAHAHAHAHA 😂❤

[julianneramirez]

Thank you so much, Sir. I just started my school year a week ago as a STEM junior and I saw this lesson in my syllabus. I was scared I wouldn't understand it but you explained it so well. God bless, Sir.

[jeraldmonroid]

this made understanding precal little easier because of the explanation thx.

Answer for assignment (correct me if i'm wrong thank you):
4x^2 + 4y^2 + 12x - 4y - 90 =0

2x^2 + 2y^2 + 6x - 2y - 45 = 0

x^2 + y^2 +3x - y - 45/2 = 0

(x^2 + 3x + 9/4) + (y^2 - y + 1/4) = 45/2 + 9/4 + 1/4

(x+3/2)^2 + (y - 1/2)^2 = 45/2 + 5/2

(x+3/2)^2 + (y - 1/2)^2 = 25

c: (-3/2, 1/2)
r: 5

Sir, what if may linear function ang given general form, you can turn it to standard but how can you turn it back to general, ask lang po. Medyo nahihirapan po ako mag solve ng naka linear yong quadratic dapat or quadratic sana.

Example po;

=4x²+4y²+40x-32y=5
=(4x²+40x) + (4y²-32y) = 5
= (4x²+1x) + (4y²-8y) = 5
= 4(x+10x+25)² + 4(y-8y+16)²= 5+4(25)+4(16)
= 4/4(x+5)² + 4/4(y-4)²= 169/4
= (x+5)² + (y-4)²= 13/2


Ito yung given general to standard, how can you turn it to general again, even though may present na linear function. Nahihirapan ako po ako ibalik, I tried transposing the ² present into the 13/2 which is close to the answer but very wrong naman po. Ilang experiment na ginawa ko po, some how I can't ask this question to my pre-calculus teacher kasi nag stop naman ako sa pag-aaral, somehow I'm learning STEM lessons online, dito rin po sa channel. I hope mabasa niyo po!

Sir question lang po yung formula po ng phytagorean theorem bakit po siya a²+b²=c²? May squared po ba dahil makakagawa ka square?

[maurivalera]

sir why do you stare awkwardly whenever you look at the camera hahaha good teaching tho!<3

[jenielyngonzales]

sir ung sa transforming SF to GF ung pangalawa ung 26-9 Po ay 17

[marygracedelgado]

I was about to say it's 17 cuz why 15 huhu and then I read the comments below then that's it Hahahahah it's 17

[gabrielayop]

Yung sa (y-1)² dba dapat answer dun is -1y? Because -1 x y = -1y then multiply by 2 is equal to positive 1y?

[Ryo_Ama]

Thank you po, perfect to dahil nag a-advance study ako kasi next week na pasukan and ang dali maintindihan at parang eto din ata yung tinuro samen nung g10 kaya familiar nako🥰

[Aleia-jn]

can someone explain to me why it is -2y if the -1 x -1 =1 when the fact the -1 multiplied by itself
