Scalars r2_w
Webvectors u,v,w in n−space Rn and salars c,d. Theorem 4.1.5 Let v be a vector in Rn and let c be a scalar. Then, 1. v +0 = v. (Because of this property, 0 is called the additive identity in Rn.) Further, the additive identitiy unique. That means, if v +u = v for all vectors v in Rn than u = 0. 2. Also v +(−v) = 0. WebArray scalars have the same attributes and methods as ndarrays. [ 1] This allows one to treat items of an array partly on the same footing as arrays, smoothing out rough edges that result when mixing scalar and array operations. Array scalars live in a hierarchy (see the Figure below) of data types.

R4 is 4 dimensions, but I don't know how to describe that... When vectors span R2, it means that some combination of the vectors can take up all of the space in R2.
