Vectors

Components

1) Separate the vector in the x and y components.

A_x =A cos q

A_y =A sin q

Addition (using components)

2) To get the resultant R add the components of R separetely.

R_x = A_x+B_x

R_y = A_y+B_y

3) To get the total size of R use the pythagorean theorem and to get the direction of R use the inverse tangent function.

R = Ö ( R_x²+R_y² )

q_R = tan^-1 ( R_y / R_x)
