If

c=|a|b+|b|awherea,b, andcare all non zero vectors, show thatcbisects the angle betweenaandb

2. Relevant equations

3. The attempt at a solution

I'm taking the approach to prove that the angle betweenbandc= the angle betweencanda

I have written the fact thata[itex]\bullet[/itex]b=|a||b|cos [itex]\theta[/itex]

However, I'm not sure how I can work the equation forcto be able to apply the identity.
