Polar Coordinates - Basic Graphing 

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

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

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

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.

@LimeRising glad you made it through the class : )

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

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

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

youre literally the best tutor

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

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

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.

who would dislike such a talent of teaching ?

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

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

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

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

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

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

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

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

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!!)

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

no problem

glad to help!

after 12 years, it stil works!!!!

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

Your videos really help dude!

glad you feel that way :)

you're a good man

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

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

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

ha, that is one of the next ones!

The only ppl who dislike these videos are college math professors

This is great, keep it up!

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

why aren't you my teacher

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.

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

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

My God! you are my hero!

That was an amazing circle..

@3:56 this made me a happy man

thanks a lot i really found it helpful

Great Job! Thank you!

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

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

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

yea, good luck with that ;)

patrick JMT, more like patrickBOSS

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

I think you draw some really nice circles haha :D

You're amazing. I love you

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

Thank you >> helpful video

do you have tutorial about relation between polar and rectangular

LOVE YOU

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

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

lol, i dont think so : )

you're great dude

better late than never i guess : )

thank you reis

I agree, the subtitles are hilarious XD

thanks! :)

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

2019 bois and gurls raise your hand.

Topnotch!!!

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

ooooooooooooohhhhhhh! I get it. :)

@Prot0n yes it is noob

cool you're left handed :)

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

Im so fucked for this final lol

i have no soul bby boy

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.

@system0system you cant even spell predominent

@system0system you cant even spell predominant

hmmmmmmmmmmmmmmmmmm
