Question

a question on vectors

Answer 1

\[\left| \left| r (x,y,z)\right| \right| = magnitude \right?\]

Answer 2

\[\left| \left| r(x,y,z) \right| \right| = magnitude?\]

Answer 3

Yes, the sign for magnitude is similar to absolute value. It is the square root of (x^2+y^2+z^2) which should give you a positive scalar number.
