thank you so much for taking the time out to help. jazakAllah wa yahdikumullah!

Hey

[@archer9322]

Always wonder the relationship between vectors and complex numbers! This video has clarified all my doubts. Thank you so much!

[@Erica-rv7ze]

Best explanation out there!

[@shauryaveersharma4739]

Nope

[@SuperstarFx]

So clear! Great job!

[@andrewzorah1562]

i have a diagram with my name lmao

Wow. Man you need to become a teacher. Thanks man

Thank you

best work ExamSolutions

Thanks

[@kamalnayanbhatt54]

You are the best !!

[@dalenassar9152]

...just being picky..."you missed one! Specifically, the plot of vector 'OA-OB' thus forming the 2nd parallelogram in the second diagram. GREAT VIDEO!!!!!!!

[@jiminsaccident4961]

Had this been explained to me the way you explained it, I would've gotten it. Ah well, better late than never. Thank you so much for your help :)

[@ExamSolutions_Maths]

I am pleased to hear that you have now got it. Best wishes.

Oh my God ARMY is also here☺️🙂🙂

[@megatron9624]

Wow I understand argand diagrams so much better

[@ExamSolutions_Maths]

Fantastic!

@cmdcs1 Yes, unlikely to be before June though

[@ashwanbhoojedhur3021]

Thank you...wel done

[@nicholasdboss3680]

awesome keep up the good work!!!!!!

[@okashakhan458]

I've question, you did z1+z2=-1+3i Why did you start from origin.? Why didn't start from -1. Please explain me.

[@aashutoshdhakal8564]

Its not vetically up or horizontal, its the distance from origin thats it

[@ellisheasley]

very clear and helpful thank you

[@chrismumbikapsis]

well taught lesson thanks

[@harshguleria69]

thanks for the tutorial chicha

[@lomertamahon1]

You make this crystal clear. Pardon the pun, why does my textbook make this simple concept so complex?

[@sohanam4943]

Bcs it's complex number

[@Ason357]

You're great 😊 Keep it up

[@alwysrite]

nice easy pace

[@stermonstermon]

where are the circle and perpendicular bisector locus? Thank you for this video :)

[@izzah310]

why did you start from origin for Z1+ Z2 at 3:23

[@izzah310]

oh nevermind that was a dumb question i get it now

[@ExamSolutions_Maths]

@@izzah310 That's good.

[@jobinsvideos]

Thanks for this woonderful 7.28 mins .. Thanks

[@sadiayasin2511]

Nice and easy explain.

[@georgiosapostolides1944]

Is it wrong if i just want to show the position of a complex number if i ommit the straight line which connects the complex number with the origin (known as modulus)?

[@MathCuriousity]

So complex numbers don’t add like vectors unless from the get go we GIVE the Z line a DIRECTION correct?!

[@joedeveraux]

Brilliant.

[@blacksamaurai]

thank you so much!

[@ExamSolutions_Maths]

You're welcome

[@MEDDY-c1d]

What about z = π + ei How to put it in complex plan Please answer

28 seconds isn't .28 minutes, it's 7/15ths of a minute, so it's actually 7.47 minutes (to 2dp, as that's then number of values we're given). The fact that I pointed this out, plus the fact that I'm here learning FP1 for no reason other than my own entertainment is why I'm so unbelievably surprised to actually have friends.

[@AksamRafiz]

Lose ur friends yet?

[@Usering150]

Here, we give a bar over Z to show that's the conjugate just like the ones we write over some repeating numbers like, 0.123123123....

[@gantaymula8309]

if z1+z2 = -1+3i the why u started from the origin???

WHY IS VECTOR BO = THE NEGATIVE OF VECTOR OB ?!

[@quieres8614]

Not sure if I'm getting a response but that last part confuses me (I might have missed something so this may be a silly question but I'm not sure ?) -- it says that line BA = BO + OA but is also equal to OA - OB. From the left side, we can see that BO + OA = -1 + 3i and on the other side, OA - OB = 7 + i so how can both of them equal to the same "length" if -1 + 3i =/= 7 + i ??

[@ExamSolutions_Maths]

Hi, I think you will find that you have missed the point as both are different and will not be the same length. On the left (in the first example) I give the result that O to C is -1 + 3i and on the right (second example) that B to A is 7 + i. This is to show the addition rule and subtraction rules of complex numbers and how they behave similar to vectors.

[@quieres8614]

Oh I see, great! I appreciate the reply, it did clear my confusion in this part of the vid. Other than that, I found this (and the rest of your videos that I've watched) easy to follow, thanks!

[@DanteDMCry]

O represents the Origin I believe, but ya 0 would suffice.
