Length of a Vector in 2 Dimensions (examples)

To find the length of a vector we simply use the Pythagorean Theorem. The components of a vector form the base and height of a right triangle. The length of the vector is simply they hypotenuse of that triangle.

What i learned here was

When we you refer to length of the vector, notations of double bar is used.

Pythagoras theorem can be used to find length of vector.

Well explained, at first i thought that even simple vectors would be hard and complicated but knowing the pythagorean theorem it's pretty simple!

Great. So calc 3 starts off with basic geometry.

Very nice video. Makes it much easier to understand. Sometimes terminology scares students off.

The part when you were finding the square root of 3 and 1, and you said it was 10. Many people wouldn't understand how you got the figure 10. I understand how you got it, but just in general it might have people that might get loss at that part. So could you just break it down, just in case their is someone thats a bit confused. Thanks. By the way love how your explaining.🖒

Complex but very well explained now I understand more about vectors

[irewolebolusemihi]

quite easily explained I was quick to understand this😇

Yes, but how does this help us solve real life problems? I'm currently studying how to use vectors to manifest and looking to see if I can blanket this formula to help my niche/market manifest their goals with vectors. ???

[MayaMcfrancwa]

that helped a lot, cant wait for the exam question

[MineCrafterCity]

Why do we use (-2) ^ 2 instead of -2 ^ 2?

[Arunasweets]

I have an exam in 30 minutes lmfao I'm so done with life rn.

[anannitabanerjee]

Why are taking negative integers when the distance from 0 is a positive number ?

[AvocadoHeadChannel]

I am going to have exam after 2 hrs and I have to study vectors, probability, and Mean range median
I an so dead rightnow

[mysteriousgamer]

I thought it would be hard af thanks you bro

[int_t]

1:44 You remind me the Pythagorean theorem

[aimichiko]

Shouldn't you also break down the final answer? I mean, you wouldn't say, the magnitude was 10 squared right?

[uou]

is a vector must pass into the point of origin (0, 0)

Funny how in math you always have to take things learnt in the past for new things.
