The function T : R 2→R3 is defined by: x ( 4 x2 ) x Show that T islinear. A proof of linearity begins by assigning v1 and v2 to be two arbitrary vectorsin the domain of T , and α to be a scalar to prove the conditions: i. T ( v1+ v2 )=T (v1 )+T (v2 ) and ii. T ( α v1 )=αT (v1 ) for all scalars α (usually α∈ R ) and vectors v1 ,v2∈T . Let v , v ∈ R 2 . Then, v = ( x1 ) and v = ( y1 ) . Therefore, x + y ( 4 ( x2+ y2 ) 4 x2+4 y2 Now, to prove linearity ...

Without distinguishing row and column vectors, we can define vectors as follows: A special type of vector is the standard vector. However, in linear algebra, we sometimes need to distinguish row and column vectors, which are defined as follows: The two basic vector operations are addition and scalar multiplication. Using these two operations only, we can combine multiple vectors as in the following definition. Another concept that is closely related ...
