Polar Coordinates - Basic Graphing

[@alvingeorge123345]

got my finals today. if i pass, it's all because of you professor

[@green2882]

so did you pass?

[@alvingeorge123345]

Lol I did. Now I'm on multivariate calc

[@green2882]

Alvin George good stuff man, keep with it. I've got many semesters left of math. I'm doing Electrical Engineering hahah

[@alvingeorge123345]

I'm in the same boat. Software engineering. No physics though so can't complain too much

[@green2882]

Alvin George niceeeee

[@kelseyevans7474]

Even after 8 years after this video was posted, it's still helpful

[@norceenhamdi]

Why wouldn't it be? Math basics are still the same.

[@keatonnixon4541]

you probably dont care but if you are stoned like me atm then you can stream all of the latest series on InstaFlixxer. Been binge watching with my brother for the last weeks xD

[@jordanandre3477]

@Keaton Nixon yup, I've been using instaflixxer for years myself :)

[@axlfabian3256]

@Keaton Nixon yup, I've been using instaflixxer for years myself :)

[@LimeRising]

Using your videos, I was able to teach myself polar graphing and pass calculus. thank you so much! truly the best math tutorial i've ever seen.

[@patrickjmt]

@LimeRising glad you made it through the class : )

[@shobhitrastogi9273]

YOU ARE PROVING TO BE A ROLE MODEL FOR MILLIONS. HATS OFF TO YOU@@

[@moonstars5678]

i honestly don't know what i would do without you. thank you soooo much

[@patrickjmt]

no, it was because of YOU! i did not take the test : ) i am happy that the vids helped a bit though

[@JTV0504]

If you had to tell someone a few things they should know going into Calc 1, what would they be? These vids helped a lot through Trig. Thanks.

[@Withlove133]

Thanks so much! This helps so much since I didn't take percal before taking cal 2 !

[@Jmf619]

You have been so much help through my semesters of calculus. Thank you! Do you have any videos on fourth semester calculus?

[@gsev38]

youre literally the best tutor

[@brianmedina3569]

Thank you for this videos. I always watch them when I'm confused on a concept or just need more help on certain sections. This videos truly help. Thank once again

[@zrhoads4439]

As you said, you don't really need the tan(a) = y/x identity for your examples, but knowing and applying that identity would greatly simplify your work for one of them. For your example, [r = tan(a)sec(a)], after your first rewriting of the equation (and realizing that sin(a)/cos(a) is tan(a), of course) you can multiply both sides of the equation by cos(a) and then apply two identities to each side: tan(a) = y/x and r cos(a) = x

[@patrickjmt]

ha! i am glad they have made that big of a difference! you should send me a box of cookies or something for that! (except i would not be here to eat them!!)

[@xXxdayXdreamxXx]

i don't get how anyone could dislike any of your videos

[@nohanahadjijamel112]

I think i had just discovered a very simple techniques to simply pass math and that is to watch your videos. #best-U

[@Barhoom9494184]

who would dislike such a talent of teaching ?

[@ohyahers]

I got an A on my last test because of you!

[@fairyatluvland]

Thank you so much! You are x1000 more helpful than my math teacher! :)

[@alyannam7782]

"What was I going to say?" LOL. Happens to me all the time! Thanks for the video!

[@patrickjmt]

no problem

[@andyatk2007]

Your videos really help dude!

[@amak1131]

Wow, we just did that in school, too:D Can't wait to see your method for it.

[@patrickjmt]

glad to help!

[@苏伏]

after 12 years, it stil works!!!!

[@patrickjmt]

glad you feel that way :)

[@patrickjmt]

ha, that is one of the next ones!

[@BlazingSky13]

Wow, this was pretty useful since my teacher barely covered this stuff for some strange reason. Also, I hear Steam notifications :P

[@MuhammedIbnSuhaylIbnAbdAlAzeez]

How do you decide which quadrants to graph when working with more complicated graphs?

[@abiwankenobi777]

so how would you graph rcosθ=4? if rcosθ is x that would mean x=4 so would it just be a vertica line on 4? my teacher didn't explain this.

[@Insert639]

Did you find an answer?

[@fasihz]

Yep that should be it.

[@playmaker8267]

This is great, keep it up!

[@ShadyToast]

I wonder what life was like for people before 2008 lol O.o

[@alexwang982]

No youtube

[@benfillman4049]

Pi KZbin was 2005

[@mohammedkhatib6290]

you're a good man

[@angelakabuno6040]

OMG I love youuuu!!!!.You're soo good

[@luisdauz6719]

do you have tutorial about relation between polar and rectangular

[@djmpvae27091978]

For a 3D graph: r = x^2 + y^2 + z^2, that means z = r tan Θ

[@tastefulbanjo7609]

Oh lord. Forgot my headphones and wanted to watch this at the public library. Thought: "hey, it has subtitles!" Couldn't stop laughing :/

[@jashar1]

D@mn it, I wish I would have discovered your videos at the start of Cal II!!!

[@lightsoff97]

why did you multiply by r in the (tanxsecx) example?

[@heyitsalex99]

@3:56 this made me a happy man

[@majidul1]

How do i graph a cardioid and archimedean spiral? I can't seem to convert them into rectangular form.

[@adoahmed8440]

thanks a lot i really found it helpful

[@idle4062]

Great Job! Thank you!

[@LameGeneration91]

4:07 the moment I realized it's a parabola.. ORGASIM!

[@zain4019]

محمد العتيبي that moment you're studying evolution in biology and read it as organism

[@jaycee_san]

My God! you are my hero!

[@Kyal4Design]

After your vids, I don't give a damn shit for what my Doctor saying :P you are GREAT man!

[@kapil33333]

Interesting😍😍😍 I would like to visualise the last one.....

[@asderfaksl]

why aren't you my teacher

[@Opethian214]

+asderfaksl He is. He is just not giving you marks ;)

[@samost7352]

patrick JMT, more like patrickBOSS

[@usmanchughtai1751]

You're amazing. I love you

[@patrickjmt]

yea, good luck with that ;)

[@thund3rd3v1l]

That was an amazing circle..

[@al-anoudcaraz8560]

Thank you >> helpful video

[@WediWelWel]

The only ppl who dislike these videos are college math professors

[@patrickjmt]

lol, i dont think so : )

[@EngHasaneen]

you're great dude

[@IamGrimalkin]

Why do you put arrows on the end of your curve?

[@bobotruong]

same in vietnam, we don't use sec and csc

[@twipie]

LOVE YOU

[@barancel11]

thank you reis

[@The4thbassguy]

ALSO Limacons with inner loops!!!! areas and junk!!!!! THANKS!

[@aj23s]

do u havt to drw the graphs ?????

[@CrzyBoy]

I think you draw some really nice circles haha :D

[@patrickjmt]

better late than never i guess : )

[@perlavespinoza]

I agree, the subtitles are hilarious XD

[@rawritscheezey]

Turn on subtitles at 0:28 "exceeds our present data of white house are sings a term"

[@ohyahers]

thanks! :)

[@markjackson6642]

Topnotch!!!

[@rrow8167]

ooooooooooooohhhhhhh! I get it. :)

[@vaniacampos9916]

cool you're left handed :)

[@ChronoTriggerMusic]

@Prot0n yes it is noob

[@wenzjayy]

BASICS??? are you kidding me? i got a nosebleed ....lol

[@xlennon781]

2019 bois and gurls raise your hand.

[@christianleone1770]

Im so fucked for this final lol

[@kakadatuot4394]

The first question gave the wrong answer. It should be x^2+y^2=4 not square root x^2+y^2=4. that answer doesn't make any sense.

[@kakadatuot4394]

1:42

[@classicrock2017]

square root( x^2 + y^2) = 2, so x^2 + y^2 = 4

[@YuTu13e]

Jesus...why can't you be my teacher?

[@jessicali4688]

i have no soul bby boy

[@ABHISHEK-nb6zg]

hmmmmmmmmmmmmmmmmmm

[@Dunwhine]

@system0system you cant even spell predominent

[@Dunwhine]
