It should be pretty simple to prove that the direction of c ˙ → is the same as the one of c → in your post. Step 2 - Find the angle between the new proposed bisector and the original vectors. Web19 sep. 2024 · I found a condition in a book regarding two vectors to have acute angle between them. I said that say a and b are two vectors then if they have an acute angle between them then $ a+b > a-b $. I am confused about this.. It would be great help if I get a convincing reason for this.
