Document Summary

5 l and rc 2 1 l a find otr. 111. 111 coso where 0 is the angle between vectors andy. Kline vectors up attail 0eo n c what y y is the angle between the two vectors. In general we call us and y orthogonal if. U o. ir o d are 22,3 i and 23,6 3 orthogonal. Hence they are parallel one is a multiple ofthe other. Eg plot the ng plane uz plane and the yzplane. Pip perpendicular vectors to theplane vector normal n o planes looklike infiniteflatpieces of paper uzplane y o. A normalreefers to a plane is a rectorperpendicularto the plane. That means it p and r are points or the plane then ptb n o. Eg find an equation of theplane passing through the point poli 4,21 with a normalvector i. Let p cu y z be on theplane y ptp o. Ln y z n l y 4 z 27.
