A ray of light is incident on a plane mirror along the direction given by vector `A = 2hati - 3hatj + 4hatk` . Find the unit vector along reflected ray. Take normal to mirror along the direction of vector `B = 3hati - 6hatj + 2hatk`.

A

`(-94hati + 237hatj+68hatk)/(49sqrt(29))`

B

`(-94hati + 68hatj+ 273hatk)/(49sqrt(29))`
