graphical Method....

1.Choose a scale and include a reference direction.2.Choose any of the vectors to be summed and draw it as an arrow in the correct direction and of the correct length- remember to put an arrowhead on the end to denote its direction.3.Take the next vector and draw it as an arrow starting from the arrowhead of the first vector in the correct direction and of the correct length.4.Continue until you have drawn each vector- each time starting from the head of the previous vector. In this way, the vectors to be added are drawn one after the other tail-to-head.5.The resultant is then the vector drawn from the tail of the first vector to the head of the last. 6.Its magnitude can be determined from the length of its arrow using the scale. Its direction too can be determined from the scale
