Do you know how to calculate the magnitude of a vector V = <a,b>?

What does your class notes say?

What does Google say?

 

[Gummg]

No

No I don’t know how to

I don't know what either say

Do you know the definition of "length of a vector"?

I don't know what either say

Do you know how to use Google and look for answer?

Hint: The length of vector <a,b> is (a² + b²)^1/2
