Summary: The x- and y-components of a vector: The magnitude of a vector: The angle q between vector and x-axis:
Adding vectors by the component method • Steps: • resolve each vector to its x- and y- components. • Add the x- components together to form the x- resultant • Add the y- components together to form the y- resultant. • Afterwards, use the Pythagorean theorem to find the R. • Use the tan function to find the angle of the resultant
