Determine the Resultant vector R=A+B graphically using the Polygon
Method for two vectors. You need to scale your vectors before to get the magnitude and direction of the Vector R using the provided Ruler and Protractor. Determine the Resultant vector R=A+B analytically using the laws of cosines and sines. For that you need to get the
Magnitude and the Direction of the vector R.
Law of Cosines: R^(2)=A^(2)+B^(2)-2ABcosgamma , Law of Sines: (R)/(singamma )=(A)/(sinalpha )=(B)/(sineta )
