The matrix for reflecting through a certain plane P which passes through the origin, is given by

 

\(\renewcommand{\arraystretch}{1.5} \begin{pmatrix} \frac{11}{15} & \frac{2}{15} & \frac{2}{3} \\ \frac{2}{15} & \frac{14}{15} & -\frac{1}{3} \\ \frac{2}{3} & -\frac{1}{3} & -\frac{2}{3} \end{pmatrix} \renewcommand{\arraystretch}{1}.\)


Find the normal vector of plane P.

The normal vector of the plane is (-12,3,7).
