A Note on Vector Notation
Although vectors in this course are denoted by placing an arrow above a symbol () and unit vectors by a hat (Â), there is more than one way of writing them.
For example, vectors can be written with an underscored line (A) or by writing a symbol in bold typeface (A). Many textbooks use the bold face notation - easy if you are typestting but not so easy to convey if you are handwriting solutions to problems!
It is important that you are aware of different notation for future courses as lecturers and authors use different (but hopefully consistent) notations.
This course will use the arrow notation exclusively.
