WebFeb 2, 2024 · From a mathematical point of view, a vector is an ordered sequence of numbers (a pair in 2D, a triple in 3D, and more in higher dimensions), and that's all there is to it.Of course, scientists wouldn't be themselves if they left it at that, so they expanded this definition. In general, a vector is an element of a vector space, period.This explanation … WebIn unit vector notation, the position vectors are r → ( t 1) = 6770. km j ^ r → ( t 2) = 6770. km ( cos ( –45 °)) i ^ + 6770. km ( sin ( −45 °)) j ^. Evaluating the sine and cosine, we have r → ( t 1) = 6770. j ^ r → ( t 2) = 4787 i ^ − 4787 j ^. Now we …

Otherwise you can use s u m { v → } or t r a c e ( d i a g { v → }). But I guess s u m { v → } would be the more "standard" notation.
