Mod-01 Lec-02 de Moivre's Formula and Stereographic Projection

[@fawzyhegab]

Great Lecture, Thank you for offering that. I've watched stereographic projection in another lecutre (selected topics in mathematical physics) but the treatment was very fast. The introduction here is slow and understandable. Thanks!

Yeah I have to say the same thing 6 years later ....

Am able to follow line by line. Clear voice. Interesting 😊

thanku sir for helping thousands of sutudents to gain knowledge by basics

[@michaelgarcia812]

Very confident instructor!

Thank you sir, great lectures on geometric interpretations of Complex arithmetic and stereo-graphic projections.

Thanks sir great lecture...

[@manoranjansahu7161]

Good Refresher!

[@theittrainersap8383]

Great course, thanks for this. I just have one question about the coordinate of the point of intersection with sphere. The lecture shows that these are t(0,0,1)+(1-t)(x,y,0). I know that this is calculated from the parametric line equation passing through the sphere. But when I try to find this result, I get stuck. Can you please explain how you found those coordinate. Many thanks.

+The IT Trainer SAP It's pretty simple, actually: at t=0, (1-t)=1, so you're at (x, y, 0) at t=1, (1-t)=0, so you're at (0, 0, 1) I would guess that the line works this way "by definition", so there's not really a way to derive it. ;-)

[@anmolabhayjain9721]

You can think of this equation as giving a point which divides the line from the point to the North Pole internally the in ratio t : 1. Then you can always select t such that this point lies on the unit circle

thank you so much sir

thanks for your video!

[@rabikantrai2355]

sir the value of the w is vare in which trems of ??

[@shankar7891]

thanks sir! i have a doubt, then how to represent a complex number inside the unit circle?? because it doesn't intersect the sphere

[@armyveteran3044]

it is represented using the southern hemisphere, when the st. line passing through north plane and XY plane is extended to meet the sphere in southern hemisphere.

Can someone give me the syllabus and textbook for this course?

golam,it's your job to do the kamla,not theirs

Yeah send me contact details 😂😂😅🤣

please remove his videos... he making math complicate....

[@AMITSINGH-ti7fh]

there r other lecture bro appriciate the effort

[@ShreyashAgrawal-mq5dy]

If you think an IIT professor can complicate things for you, maybe you can not learn from anywhere. He has been appointed for giving this lecture for a reason bro and you need to respect that.
