Nice, easy and quick example. I hate videos that go on and on irrelevant stuff. People just want to know how to calculate something and thats it. Very good job! What program are you using to visualize the vectors?

What is I wanted to determine both the acute and obtuse angle between two vectors? Thank you for the help

I think if the dot product of two vectors, v and w, is negative, then the angle between vector is Obtuse. if the dot product is larger than 0 (positive), then the angle is acute..
