Question

Consider two vectors A and B with angles (0.) between their directions, as shown.
Show that the magnitude of the resultant vector C is given by the law of cosines
C = A2 +B2 - 2AB cos e​

Answer 1

Explanation:

between their directions, as shown.Show that the ... as shown. Show that the magnitude of the resultant vector C is given by the law of cosines. C = A2 +B2 - 2AB cos e .
