How do you sqaure a vector?
Is it the magnitude of the vector times the vector?
You can't "square" a vector, because there's no distinct "multiply" operation defined for vectors.
The dot product is a generalization of multiplication to vectors, and you can certain take the dot product of a vector with itself. The resulting quantity is the squared norm of the vector.
would this mean just the square of each term added together?
ive tried this but then end upwith an answer different to the one given, i have a factor of sin($) missing.
Maybe if you state the question, and your attempts at the question, then it may be possible to answer you.
