Find coefficients a1,a2 and a3 such that (1 2 1) = a1V1 + a2V2 + a3V3.
Help please
Hello, al1850!
No one is responding because we can't read the problem.
Obviously, there's a typo . . . and it still doesn't make sense.
Find coefficients a1,a2 and a3 such that (1 2 1) = a1V1 + a2V2 + a3V3 . ?
$\displaystyle A \;=\;\begin{bmatrix}\frac{1}{\sqrt{2}} & -\frac{1}{\sqrt{2}} & 0 \\ \frac{1}{\sqrt{2}} & -\frac{1}{\sqrt{2}} & 0 \\ 0 & 0 & 1\end{bmatrix} \;=\;\begin{bmatrix}v1 & v2 & v3\end{bmatrix} $ . ??
I would guess that the "coefficients": $\displaystyle a_1,a_2,a_3$ belong to $\displaystyle A$ (somehow).
But $\displaystyle a_1v_1 + a_2v_2 + a_3v_3$ is a constant.
. . It can not equal a matrix: $\displaystyle \begin{bmatrix} 1 & 2 & 1\end{bmatrix} $
Please state the original problem . . . carefully.
Hi,
Maybe this is the same as here : http://www.mathhelpforum.com/math-he...-question.html
