... To see if {~v2 } is linearly independent, we need to solve the vector equation: x · ~v2 = ~0 That is, x(3, 0) = (3x, 0) = (0, 0). The only solution is x = 0, so {~v1 } is linearly independent. Note: If a set contains only one vector, then it is linearly independent if and only if the vector is a non ...

... (a) Construct the quadratic interpolation polynomial p2 (x) which interpolates the data. (b) If the function being interpolated was in fact f (x) = x3 + 2x2 − 1, derive a tight upper bound on the error in using p2 (x) as an approximation to f (x) on [0, 2]. 2. This problem concerns orthogonal polyno ...

Systems of Equations: Introduction
... To solve a system of linear equations by elimination requires one of the variables, in both equations, to have opposite numerical coefficients. This can be achieved by multiplying one or both of the equations by an appropriate value. When this is done, the equations are then combined. This will elim ...
