Sir thank u so much. I got my annual examinations next week and math is the 2nd exam... I completely forgot how to do this but you explained it so simply...
thank you. what i like about your videos is you give all those little details that many'd just skip in their (very amazing) videos. those are exactly what i am looking for so many times.
Thank you so much! I was unsure how the awnser of a problem where I have to find argument of a problem simply indicated as being -3i (so the real axis (Re) is 0), but you explained it perfectly in how the angle is measured from different segments. Because the point is in the 3pi over 2 line, the angle is pi over 2 (I know it's shown as a minus, but my teacher always siad an angle can never be negative so that's what had me confused and I THINK I understand it now, thanks to you). I would never have even known how to ask about this, but you awnsered it so perfectly, thank you sooo much!
A big thanks to Exam solution......its really helps me much to understand maths in a descent and easy explanation.....you removes my mathofobia slowly ...
I have a question. Let's say z=1+i Argument of z would then be equals to 45 degrees. How about the argument of 2z? Do you take 2 times 45 degrees? Or is the argument of 2z still equals to 45 degrees?
Bruh...u explained this within 16 mins and 49 seconds and made me understand while my teacher explained it over an hour and i still couldn't understand.
It's much easier to just consider this rule: argz=tan^-1(y/x) (+/ - pi for fourth and third quadrant respectively) i.e. Add pi if z on the argand diagram falls in the top left quadrant. Subtract pi if z on the argand diagram falls in the bottom left quadrant.
I just understand that if the real number is negative then you are going to have 'negative(π negative the answer in rads)' Thank you so much sir jah Bless

The word is quadrant. The first quadrant is the section in the top right of the cross going from 0 to 90 degrees. The 2nd quadrant is the top right going from 90 to 180 degrees. The 3rd quadrant goes from 180 to 270 degrees and the 4th quadrant from 270 to 360 degrees.

You have been helping me since i started a-level and are continuing to help me throughout me degree! THANK YOU!!!!!
Dan Waggon Pleased to be of service. Having your support means a lot.
Saaaame im currently in A-levels tho
Yeah im currently doing Pure Maths in A levels Goodluck

This tutorial helped me so much. I couldn't believe how much I learnt within the space of 16 minutes. You have an excellent teaching style!
Got an A* in FM because of you legend
This guy! I swear without him I may as well just forget maths and further for a-level. Keep doing what you're doing! ❤️💪
It’s been 9 years, and it still helps students like me.
My maths due date is tomorrow and here I am because I was lost in class.
Make sure your calculator is in radians mode. I suspect it is in degrees mode.

thank you sooo much, really helpful. when i get a job im donating to all the people who make videos like this on youtube
I wish I knew this site in my Ordinary and advanced level days. I'm a Maths Teacher, and it's really helping me out.
Glad it's useful to you!
Sir thank u so much. I got my annual examinations next week and math is the 2nd exam... I completely forgot how to do this but you explained it so simply...
Considering this video is over 8 years old you probably won’t read this but Thankyou so so much you have an excellent teaching style
Thank you so much. I was completely lost in class, then I found this video, and I finally understand! 😊❤❤

thank you! i thought this topic was so confusing when i did it in class, but this made perfect sense
I was very confused with handling signs... After your explanation i feel m blessed... Thank u
That's good.
You are the best teacher ever. May God bless you.
Great vid! Another care should be taken when talking about Arg(z) and arg(z).
Thank you sir this video is very helpful to me. I was not understanding this topic in my collage.

Thanks
Thanks a lot you solved a big problem
Unbelievable video helped me a lot. Thanks
Good to hear. Best wishes.
it was very helpful thank you
Great help! Saved me big time!
question? do you require to keep your calculator in radians mode all the time for complex numbers?
Thank you so much for taking the time to do this. You are amazing.
Thank you soooo much !!!! you are the best. I spent the whole day looking for explanation but no one was able to explain it that clear . THANKS!
THANK YOU! I LOVE YOU! you are saving me
Brilliant explanation 🙏
Nice, very clear. Thanks 😊
Thanks, this was helpful.
You're welcome!
This was so helpful, thank you!

BEST TUTORIAL DUDE KEEP UP THE WORK!!!!
Thanks - my website makes navigation easier though.
Its chewsday innit?
Thanks a lot, i was reading on my textbook and didnt understand much but you got me in 17min thanks!!
No problems - Thanks for using the website.
Thank you so much!!! This was explained really poorly in my lectures
Hi
I have a question.
Let's say z=1+i
Argument of z would then be equals to 45 degrees. How about the argument of 2z?
Do you take 2 times 45 degrees? Or is the argument of 2z still equals to 45 degrees?
Still 45 degrees. The mod is doubled though.
bangin vid, straight to the point. cheers
What about finding complex when given, modulus and arg
This video really helped!! Thanks a lot!!!
thanx.... u r awsm ....u r great,,.. i hate maths at a tim but aftr tautng u i love maths,,thank u
Best explanation!
Thank you so muchhhhh... I could understand very easily 😆😆😆
Amazing, thanks alot
This video literally saved me after a long time of trying to figure it all out. Thanks and subbed!
Bruh...u explained this within 16 mins and 49 seconds and made me understand while my teacher explained it over an hour and i still couldn't understand.
seriously this is very helpful!
thanks a lot!!
Very helpful thanks
very precise and to the point. thanks
Yo made it look so easy thank u
how do you know where to label the acute angle (alpha) on the line of Z
Massive thank you! So beautifully explained
thanks
It's much easier to just consider this rule:
argz=tan^-1(y/x) (+/ - pi for fourth and third quadrant respectively)
i.e. Add pi if z on the argand diagram falls in the top left quadrant.
Subtract pi if z on the argand diagram falls in the bottom left quadrant.
a real life saver ! thank you so much for making these videos.
Thank you for your support
I just understand that if the real number is negative then you are going to have 'negative(π negative the answer in rads)'
Thank you so much sir jah Bless
This is awesome! thanks for explaining it so clearly! I have been following your channel and its really good!
Thanks for your support
fantastic as ever , makes it so easy thanks
Great video sir
Brilliant - looking forward to my exams now!!
How was the exam
thank you sir amazing work
God Bless You
And you
if u can calc. theta in degrees ur job is done. angle in rad = (ang in deg) * pi / 180
Wow! Thank you so much
May God bless you sir...Thank you very much
And you
thank you very much

Is there a way to get the inverse tan answer without a calculator?? Please help this is helpful
I don't think you're taught that in regular maths or further maths a level
this is still helpful even after 8 years
Maths is timeless.
THANKS A LOT. one more doubt. how we get the value 1.17 rad for tan inverse 12/5. please elaborate. i cant able to get that. please and thanks a lot
How often is it referred to as the ‘absolute value’ rather than ‘mod(z)’
Big help
Thanks
Thank you so much! This video has helped so much, I really appreciate your work
Thanks for showing your support
you are GREAT, thanks a lot!!
in the third quadrant , why did you put negative pie? thx
Helped a lot👍
can you tell us how to calculate radian without the calculator ? please ty
Yes
also , length can not be negative right?
