WebDetermining the resultant in three dimensions Example. Given \(P(1,4,8)\) and \(Q( - 3,1, - 4)\), find \(\overrightarrow {PQ}\).. To do this, think of yourself in the position of point \(P\).How many units in each direction would you have to travel to reach point \(Q\)?A quick way to do this is to subtract the values of the coordinates of \(P\) from the coordinates of … WebRemember to look carefully at which angle you are being asked to name. The reflex angle is the larger angle. It is more than 180° but less than 360° If you choose the smaller angle you might have an Acute Angle, or an Obtuse Angle instead: The larger angle is a Reflex Angle, but the smaller angle is an Acute Angle
