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 ...

Adam Smith Father of Economics Responsible for Division of Labor 1776: Tasks are subdivided into individual jobs Employees perform only the tasks relevant to their specialized function Jobs tend to be small, but they can be performed efficiently Proposes that production can be increased by dividing labor on to similar tasks Frederick Winslow Taylor Scientific Management 1911: Developed standard method for performing each job Selected workers with appropriate abilities for ...

Linear Transformation correct answer: A function T from Rm to Rn is a L.T if there exists an n x m matrix such that T(x)=Ax for all X in vector space Rm The columns of the matrix of a linear transformation correct answer: The matrix of transformation has column vectors T(e1), T(e2), etc. where e's are the standard vectors Linear Transformation(proofs) correct answer: 1) T(kx)=KT(x) 2) T(x +y)=T(x) +T(y) (x and y in Rm (starting Vector space) and K is a scalar ) Distribution Vector...
