Can it be zero? •Answer: Distance is non-negative for the same reasons as magnitude (it is a measure of length, and the formula squares the values). •The distance between two identical vectors is 0, otherwise distance will be positive.

WebA unit circle has a radius of one. Cosine is the x coordinate of where you intersected the unit circle, and sine is the y coordinate. Or if you had a vector of magnitude one, it would be cosine of that angle, would be the x component, for the, if we had a unit vector there in that direction. And then sine would be the y component. WebIt is convenient to draw vectors starting at the origin, but it is NOT necessary. 5 is just the vector's LENGTH, and -3 is just the vector's HEIGHT. You can draw the vector starting at any point on the graph, but you have to make sure it has a length of 5 and a height of negative 3. For example: If you drew the vector starting at point (1, 1 ...
