Using these unit vectors helps one keep track of the direction of the components. This means that I can write the above example for vector A as: An Example: I think you are ready for a real example.

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

Here is an example (using the same vector from before): And in magnitude-direction format, it would be: I am not too found of this format. First, if you want to add vectors, you need to find ...
