Any vector \(\displaystyle <p,q,r>\) having the property that \(\displaystyle <p,q,r>\cdot<i,j,k>=0\) is perpendicular to \(\displaystyle <i,j,k>\).Hi, If I have a vector V = <i j k> and a plane in form of ax + by + cz + d = 0
is it possible to find a vector \(\displaystyle \frac{\pi}{2}\) from vector V??
