Use the following vectors to answer the question.
u: <-1,7>
v: <6,4>
What is ||u||2?
To find the Euclidean norm (or length) of a vector, also known as the L2 norm, denoted as ||u||2, we can use the following formula:
||u||2 = sqrt(u1^2 + u2^2)
Given the vector u: <-1, 7>, we can substitute the values into the equation:
||u||2 = sqrt((-1)^2 + 7^2)
= sqrt(1 + 49)
= sqrt(50)
Therefore, ||u||2 = sqrt(50).
