@@shardulnewasker2021 Since there is a given direction NE and no given angle, it is assumed to be right in the center of N and E regardless of how far he go. And so its 45 deg
So I have one question. It might be stupid. c^2= a^2+b^2-2cosC. This is what you used in the second problem. So is this like a formula which we always have to use or that negative sign is for the fact that the initial velocity is taken as negative. Im just starting all of this. So it will be great if you can help out. That's all. And thank you for this great video.
Sub Zorah Vas Neema this is something called cosine law, which is used in trigonometry (when you need to determine a certain angle or side length of a triangle). It’s probably easiest if you search up videos on cosine and sine law on UA-cam to get a better understanding of it. Hope that helps!

Are you dumb? Listen to what he says, he introduces the question initially as a sum of 2 numbers, then clearly poses the question as a sum of 2 vector quantities, ie displacement. No con here, just a logical progression in the argument, exactly what you would do when teaching this concept.
God bless you sir for making me understand more of this stuff. Please help with elecric circuit
Hey mate,
did you just assume that the angle was 135 degrees. (at 16:51)
or
is there a way to work it out!
plzz answer if you can.
thankyou
I think that comes from the NE which has no given angle, and then assumed to be 45 deg.. And so 180-45 deg is 135 deg
@@villaluzchristianjay9324 but why did he assume 45 I don't get the

@@shardulnewasker2021 But when there is an angle given, i.e. 30m/s 30 deg NE. Then it is what it is.
@@villaluzchristianjay9324 so we just assume and that's how it works 🤣
How did you get the angle value of 135 degrees in the second question
I didn't get how you got 135 for the included angle for example 2
Thank you for your explanation sir🤝
You are welcome
great stuff

What is 1D vector and how to represent on graph ?
Where did that inverse tangent come from... I am confusion
A bit too late, but does anyone have the link for this calculator that was used with our arrows?
Your lucky i read the comments 😂
And what is the point of vectors. Why did the concept come about and how did it come about? What did they want to accomplish? Why is it important?
do you always need to find the direction even if the question does not demand so?
Usually yes, unless the question specifically asks to find the magnitude only.
Okay, thanks.@@PhysicsHigh
What is displacement.
Pls which app did you use for the video
I use interactive whiteboard software called Promethean Inspire
@@PhysicsHigh Tnx
how did you get 13km at 12:37?
Square root of 169
very helpful , thank you
How did you get 19.1?
Abigail McAllister its value of x by sin inverse
It is called the law of sines
What software did you use to show the vectors?
I use software designed for interactive whiteboards. Promethian Inspire.
Umm how did you do sin x
Vector oh yeah
Piranha gun oh yeah
Plz explain dot and cross products plzzzzzzzzzzzzzzz
Will think about it. Few topics on my list. Dot products is not high School material.
Please explain further

haaaha you had to do that

You came here because of that show too?

Prexxo thanks
after 5 UA-cam videos on vectors I still don't understand ;_; I'm so fucked
This happens to me a lot when it comes to math, chemistry, physics, and biology.. This is why I don't like learning 😠
if u dont understand u should definetely try some another subject :)
Worst video i have ever seen
The way is is speaking is hilarious
You're a con-man. You pose the question, "3 + 4 = ?", then you change your language, "3 METERS", which is a DIFFERENT question than 3 + 4.
