To add two vectors, a[itex]\rightarrow[/itex] and b[itex]\rightarrow[/itex] we use the formula [itex]\sqrt{}[/itex]a2+b2+2abcosθ
where θ is the smallest angle between vectors a and b. Is there any way I can use the bigger angle to calculate the sum ? It's not a homework, just a question from my intution.
I have attached a pic also... Thanks in advance for help
