An EcoVec is a reference-counted clone-on-write vector. It takes up two words of space (= 2 usize) and has the same memory layout as a &[T] slice. Within its allocation, it stores a reference count, ...

Subtracting a vector is the same as adding a negative version of the vector (remember that making a vector negative means reversing its direction). \(\left( \begin{array}{l} a\\ b \end{array} \right) ...

Practise using vector components when adding, subtracting or calculating the magnitude of vectors ahead of your National 5 Maths exam. Revise using vector components to add and subtract vectors and ...

Any vector can be expressed as a sum of a number of other vectors. The vectors which are summed are called the components of the original vector. When you want to add and subtract two dimensional ...
