WebbSpecifically, when \theta = 0 θ = 0, the two vectors point in exactly the same direction. Not accounting for vector magnitudes, this is when the dot product is at its largest, because \cos (0) = 1 cos(0) = 1. In general, the more two vectors point in the same direction, the bigger the dot product between them will be. The magnitude of a vector is shown by two vertical bars on either side of the vector: a OR it can be written with double vertical bars (so as not to confuse it with absolute value): a We use Pythagoras' theoremto calculate it: a = √( x2 + y2) A vector with magnitude 1 is called a Unit Vector. Visa mer We can also subtract one vector from another: 1. first we reverse the direction of the vector we want to subtract, 2. then add them as usual: a − b Visa mer Now ... how do we do the calculations? The most common way is to first break up vectors into x and y parts, like this: The vector a is broken up … Visa mer A scalar has magnitude (size) only. A vector has magnitude and direction, and is often written in bold, so we know it is not a scalar: 1. so cis a … Visa mer We can then add vectors by adding the x parts and adding the y parts: The vector (8, 13) and the vector (26, 7) add up to the vector (34, 20) When we break up a vector like that, each part is called a component: Visa mer
