Complex Numbers 2 - Argand Diagram (Modulus and Conversion from one form to another)

This video teaches how to find the modulus of a complex number, how to change the form of a complex number from Rectangular to Polar form and from. Rectangular to Eular form. This video also teaches how to draw the Argand Diagram of a complex number with examples.

[@yusuftijani]

Thanks you very much sir r=√373 and the Amplitude is 21.25

[@jonahemmanuelofficial]

Well-done 👍

[@Derrobe]

You are awesome 🎉

[@jonahemmanuelofficial]

Thank you 👍

[@Mayblac002]

Sir if i want to calculate eulars form with the question in radian how will i get it because the theta is not a whole number

[@jonahemmanuelofficial]

360° = 2(pie) rad Use that for conversion

[@frederickchibuike]

You're good Please discuss Riemann surface for me and series involving trigonometry functions

[@jonahemmanuelofficial]

Thank you, ok.

[@JuliaJohn-l7i]

sir, the modulus of r is the square root of -275, with an amplitude of 21 degrees. On the Argand diagram, it lies in the second quadrant because y is positive and x is negative.

[@jonahemmanuelofficial]

Welldone...!!!!

[@yasiryusufabubakar8133]

please can you explain how you use to get your (tan inverse) thank you

[@jonahemmanuelofficial]

Get it here: kzbin.info/www/bejne/qZOmamauppJgobMsi=ZiG4Kfn79JcmmISc

[@KennethNambasa]

Aaa u have made me well versed

[@jonahemmanuelofficial]

Great.

[@godswillchuku916]

You're doing well Sir

[@jonahemmanuelofficial]

🙂

[@Feli...07-tt4eh]

God bless you🙏

[@jonahemmanuelofficial]

Thank you 🙏🏻🙏🏻

[@hopeessang6861]

Sir what how do we calculate the tan inverse without using calculator

[@jonahemmanuelofficial]

Please use a calculator

[@hopeessang6861]

My school does not accept the use of calculator

[@JamesAwusinu]

Superb

[@jonahemmanuelofficial]

Thank you 👍👍👍

[@atolagberola]

I love the class, but based on the first example, is the square root of 197 the final answer, can't we simplify further?

[@jonahemmanuelofficial]

If you can, sure 👍👍

[@atolagberola]

okay sir @@jonahemmanuelofficial

[@MathwithWaqasShah]

nice video dear

[@jonahemmanuelofficial]

Awesome. Thank you

[@MwansaJoy-wb9jq]

Sir why are you not subtracting the fitter from the angles in the quadrant

[@jonahemmanuelofficial]

Already corrected in the next video, here: kzbin.info/www/bejne/p5zKoqqYpb2GgdU

[@Im_bjay]

Sir I don't understand. I thought that i=√1, then y did u make i =1 in the beginning of this lesson?

[@jonahemmanuelofficial]

i = √ (-1)

[@bmktechprofessional]

I= /(_1) I²= -1 ̳ =I I⁴=1

[@classicmedia001]

Why didn't you add the i in the 2/41 i.. shouldn't it be (2/41i)^2?... Check the 12:29 of the video

[@jonahemmanuelofficial]

Check here 0:10

[@Nuwe-AmanyaOwenPatrice]

Do you also give for other course units

[@jonahemmanuelofficial]

👍

[@Nuwe-AmanyaOwenPatrice]

@jonahemmanuelofficial ok I'll be following

[@jonahemmanuelofficial]

@Nuwe-AmanyaOwenPatrice ok

[@Nuwe-AmanyaOwenPatrice]

Am meaning statics and dynamics, computing tools etc

[@nanjulzingkur9677]

r=sqr of 373 Amplitude =-21.30 The argand diagram in forth courtyard

[@nanjulzingkur9677]

Quadrant

[@jonahemmanuelofficial]

Awesome.. welldone

[@jonahemmanuelofficial]

Great...!!!

[@PraiseChi001]

I don't agree with your argand diagram position it suppose to be in the second quadrant

[@Lyrics323]

I feel bad for people who judge u before even watching your videos, they r missing out a lot

[@jonahemmanuelofficial]

Hahahha... guess so too

[@anitaahimbisibwe8426]

Can I get more questions about this topic

[@jonahemmanuelofficial]

👍

[@shadrachfahn1013]

I'm bit confused with example three, I did multiple 9 by 64 and I got the denominator, but multiplying 4 by 49 I didn't get the numerator right. Please take it step by step. Please❤❤❤

[@jonahemmanuelofficial]

Okk

[@JaraHuluka]

Please chapter one about rules of inferences

[@jonahemmanuelofficial]

Should be there, check

[@ChineduDesire]

The teaching was nice but can you give me a hint on how to go about fit a square root of a complex number Like square root of 16 +8i

[@jonahemmanuelofficial]

Check next video on complex numbers

[@Natty-f5f]

I have gotten -7/4+1/4i

[@jonahemmanuelofficial]

Welldone 👍

[@Joedancer7]

Plot the affix of complex number z = 2 5+i

[@Joedancer7]

Please do it

[@PaulMwenda-vs3ys]

[@alamanjovictor1331]

Sir i tap from your grcae 😊

🙏🏻🙏🏻🙏🏻

[@LarianWorlaliYevuyibor]

please can you leave your answer in rands

[@jonahemmanuelofficial]

If asked to, sure..!!!!

[@jonahemmanuelofficial]

If asked to, sure..!!!!

[@FortuneRoxan]

I got 1/2+i

[@jonahemmanuelofficial]

Try again please.

[@AcheampongBlessing-w3w]

U do all
