DeMoivre's theorem with How to Write Complex Numbers in Polar Form

PreCalculus! Let us be your online math tutor! How to write a complex number in polar form and then use DeMoirve's theorem to raise that complex number to a power and then write in rectangular form again.

You made this look so simple. The way you've explained this is truly an art

[@phoebecooper7340]

Thank you so much for this video! Very few on UA-cam have worked a complex power problem in quadrant IV, which is what I was needing. Appreciated so much!

[@MathHop]

You're welcome! I only do problems that my subscribers email me. Feel free to send me problems when you're struggling

[@levis1742]

Why are you so underrated ? This is a good tutorial.

[@ameenah6472]

Wow. You just explained deriving the theorem in such a simple way that I didn't know we were deriving the theorem until you were done! It was so easy to follow, I honestly didn't believe it could be as simple as that. ♥️

[@melanie3089]

Thank heavens for this video!!! I have been trying to solve the same problem for 2 days! You are amazing!!!!

[@hlangananizolani5348]

Thank you so much for being straight to the point and so simple, this is really helpful

[@danny-wd8cd]

This was a really good video, it helped because the lesson in my textbook says everything very complicated and just lists formulas, not how to get their values. Thank you :)

[@lordior_]

Sorry about your arm but you're the best teacher thank you

[@kledabenjaminkallo6197]

great presentation, I learnt a lot from this. thanks

[@violettiourestinpeacetechn4742]

Thank you! This helped very much!

[@sajademad117]

This is really helpful! Thanks a lot.

Thank you so much...thats very well done.

[@adelaidedubois9264]

this saved me today, thank you so SO SO MUCH

[@davisnganga6266]

Nice solution. Well explained.

[@airwrecka9036]

such a good video! thank you so much!!

[@NabilaAisyah]

Good sharing!

[@aslaamosemo5388]

Hi, am thankful of your maths share, it's really helpful here in Kenya

[@obasimatictutorial]

Interesting and its jus open my eyes to something now☺😀

[@idagizaronald7691]

Well explained
Good work

[@bushendichcaleb4141]

It has been so wonderful for me, thanks so munch

[@JamesKanyesigye]

Thanks for your help

[@michaelechutem995]

I love what u did nice tutorial

[@iqraali9671]

Nice one, best solution ever, thank you😊

[@ebronmfunka6714]

I love your explanation mom keep it up.

[@tajpa100]

this is an approximate value. The exact value is -644+960i

[@paulkaranja8077]

Wow thanks...really helpful

[@serinacat4781]

Great video

[@zianiera]

That's well explained

[@malcomtech6122]

The angle should be 360-59 correct me if um wrong

[@menakasreemaniam849]

I am curious too since R is in first the first quadrant

[@marcan9128]

Thank you so much ❣️🥰

[@polokonketlane140]

Thank you 😊

[@sandyekip2538]

Please could you do a video on industrial probability, thanks in advance.

[@kennedychitanhu9890]

Thank you

[@nardinomuchongo6080]

Thanks Ma'am

[@akedisolomon7175]

This is true mathematics

[@Devdidthat]

Good vid thanks for help wish me luck on my final!!!

[@MathHop]

Good Luck!

[@christofyeramsanchezmontes2659]

Since tan to the negative 1 came as a negative dont you need to substract 180 degrees from it?

[@NesihaTube]

Helps he a lot 😇

[@jdjjdjdjfjdj6586]

Thanks alot

[@janakamohotti]

Excellent

[@ashleynyamuripa4403]

Sorry l want to ask, since we have our complex number in the fourth quadrant, when we say 360- angle shouldn't that be our actual angle?

[@Danny-ym5qn]

I love you!!!

[@matts2565]

Thanks much

[@joelkyan7712]

Given x2y-x3y3+2=0, evaluate dy/dx at the point(1,2) thank you.

[@davidliu3463]

nice video, it might just be better if you present with a whole number modulus and sata.

[@akedisolomon7175]

Very intersting

[@fauziamohammed9521]

Kindly check the angle.. Since we have it to be in the 4th quadrant.. Won't it be 360-59

[@noorsyahirahasyikin6239]

hi sorry, the argument should be in degree or radian

[@tauancosta20]

Can someone explain to me why tanˆ-1(-5/3) ended up being -59.04? I got the part where it was converted to degrees, but I don't seem to understand how it was broken down.

[@thenewgeneration811]

Did you figured it out?

[@user-xy9ir3kc6g]

How did you get 59.04

[@garrettdurant4855]

lovely

[@serinacat4781]

Hi, there. I don't know how to send emails to you. I want to ask how to factor higher degree polynomials? Thanks in advance. 😃

[@MathHop]

Hi! Send problems to [e-mail]

[@ngndnd]

hi I have a question on how to solve something like z^5=-243i im taking a course on khan academy and the explanation is so confusing

[@NATURE-dx6ic]

ua-cam.com/video/J6TnZxUUzqU/v-deo.html

[@kerrynji5871]

the angle aint correct you didnt consider the quadrant thus you forgot t do 360-59.04

[@melodramphanter4770]

Solve this one for me (1+I)^1/3

[@nathidj8595]

Hello ma'am I this massage finds u well ..... I think u made a mistake the reference angel should not be not negative actually am trying to say u can't find the angle using negative values

[@nanayang3736]

Sorry but just wanna understand whether the -236.16 in the final answer is in rad or in degree? it seems to me that it's in degree although you didn't write the degree symbol.

[@ceromat2022]

Another example: ua-cam.com/video/iAluayOFV-o/v-deo.html

[@user-qz7ps4wp5l]

One step is missing.

[@majestic7768]

Which one

[@aslaamosemo5388]

Your channel is really helpful and we're requesting if I can get your email address so that I may be able to ask you for more help in mathematics
