TWO GRAPHICAL METHODS
PARALLELOGRAM METHOD
POLYGON METHOD
TWO ANALYTICAL METHODS
LAWS OF SINES AND COSINES
COMPONENT METHOD
same with the parallelogram method and polygon method, except that instead of determining the magnitude and directions of the resultant vector by actual measurement,theyare computed using these laws
LAWS OF SINE AND COSINES
formula for laws of sines and cosines
R2=a2+B2-2ABcostheta
DEGREE FORMULA LAWS OF SINES AND COSINES
b/sin theta=r/sin theta
for two vectors in same direction the angle is?
ZERO
the direction of the resultant with zero angle is?
SAME DIRECTIONS
