When two vectors 1 and B are drawn from a common point, the angle between them is

Question:

When two vectors 1 and B are drawn from a common point, the angle between them is Φ.

(a) Using vector techniques. Show that the magnitude of their vector sum is given by √ A2 + B2 + 2ABcosΦ

(b) If A_(vector) and B_(vector) have the same magnitude, for which value of ϕ will their vector sum have the same magnitude as A_(vector) or B_(vector)?
