Complex Numbers - Graphing, Adding, Subtracting

[rabbidfishy]

I'm probably going to find this out tomorrow morning, but I need to find a polynomial function with two complex numbers... I got one by some educated guessing that might not even be right, but i'm having a problem with a two degree polynomial that has the zeros of i and 1-2i... did you answer it here and I just didnt understand, or is this something else entirely?

[chrissyBduh]

You just explained more to me than my college algebra teacher has in a 50 minute class 3

[lukester1125]

thanks mr J sucks dick

[MrMig3]

youre the man, seriously youre awesome men, becuas you use you time to make these videos for us, if you ever come to mexico, youre a genius too, if you ever come to mexico ill buy you a beer men or anything you like haha

This is so helpful. But in the add/sub can you please tell me why you changed (6+8i) to 6-8i ? Why did you change the positive to a negative when you bought the number down out of the parenthesis?

[TheAncientEmperor]

@tanquantwal notice that in front of the parenthesis is a minus sign -(6+8i) so he changed signs from -(6+8i) to -6-8i

[tanquantwal]

@TheAncientEmperor Thank You. I never understood it fully.

[TheAncientEmperor]

@tanquantwal You're welcome. Glad i could help :)

should get youtube partnership and make money.

You're my savior ! I wish you were my teacher you make things so vivid and understandable ! keep it up, algebra 2 students all around the world thank you, already have a supporter from florida !

[007Marauder007]

Do you have any videos for De Moirvre's theorem? Could really use the help.

[007Marauder007]

@007Marauder007 *De Moivre's Theorem. Excuse the typo

[sultanx2010x]

thank you allot

[aba2185]

when you distributed the - into the 6 why did it become -6i ?

[12Razman21]

ur the best thank you!!

[Moonwalker166]

Fantastic!! Thank you!!

[DirrrtyDutchMTRFCKR]

are you a teacher :P? Really nice video, helped me a lot

[patrickJMT]

@DirrrtyDutchMTRFCKR i used to stand in front of a class and bore them, yes. but no more!

[Wonexwo]

Thank you very much for your videos, My teacher requires us to write down her notes while she's teaching so I don't ever find time to listen to her explaining it... watching your videos really helps clear things up :D

[keetley789]

Great help, but It would be good if you could show how to add say (10+10j) and 120, using polar and rectangular, thisis because I have a question to do and it's doin my head in!!!

[yaguang]

Your line drawing skills are pretty straight!

[JKNOWSALL]

Question, Why Did +8i change to -8i

[edajyamMie11]

thanks a lot mr. patrick....

[ry8an25oliver93]

I heard somewhere that the Imaginary Axis is the same thing as the z-axis. Is this true?

[MushroomManiaTV]

IS - AND - =-

[pcnerd1010]

OMG! THANK YOU for this!!!!! This helped me more than you could possibly imagine!

[awesomeness781227]

Hey, your videos are great, but I think you should do some videos on polar coordinates, the polar form of a complex number, De Moivre's Theorem, and finding complex roots. Stay awesome!

[msgeminigal]

Great info!

[almskt2007]

you're the best teacher in the world ,,,

Just I have a question in the first equation the solution is going to be 9+i or I'm wrong ,,,

[Alejo1691]

thank you ^^

[01supra]

omg dude your the best when i have maths problems i always look for the guy with the black marker an white paper

[duku013]

This is gr8 I can now figure out the tricks of adding/subtracting.

[jhnb91]

isn't 8 minus seven equaly 1 though

[snoopster2009]

Turn on annotations, he corrected that mistake.

[hOneybaBey123]

OMG THANKS SO MUCH !

[mixtapemessiah13]

thank you foe everything . i watch all your your video

[patrickJMT]

u are welcome!

[Halocuber]

Thank you , now I won't failed my Algebra 2 test tomorrow. Seriously , thank you for using your valuable time to make this GREAT video.

[patrickJMT]

no problem! good luck on your test : )

[patrickJMT]

yes, we all make mistakes!

nothing made me happier in college than when my calculus teacher would get stumped on a problem! it is nice to see that everyone is mortal after all!!

[korrisha]

Wow you make math easy gonna add you in my favourites I am doing a mathematics major here in trinidad my lecturer is not that well into explaining so most times I do not understand but you your work is great I love maths you really opened new doors for me please put up videos on inequalities at university level keisha

[GRX13]

Great job, but there's a mistake at 2:47. It should be 9+i instead of 9-i.

[patrickJMT]

ops! thanks!!

[petercourt]

Pretty basic, but still useful, thanks.

[patrickJMT]

yep, very basic. but if you do not know it, where else would one start? : )
