13 In the following cases, determine whether the given planes are parallel or perpendicular, and in case they are neither, find the angles between them.
(d) 2x – y + 3z – 1 = 0 and 2x – y + 3z + 3 = 0
whose direction ratios are and whose direction ratios are ,
are said to Parallel:
And the angle between is given by the relation,
So, given two planes
So, applying each condition to check:
Thus, the given planes are parallel to each other.
