Best ResponseYou've already chosen the best response.0the first one is this right: [0] [0] , algebraically it means 0 units across and 0 units up...geometically it is basically a dot. the second one: [3] [4], geometrically it is a line that is drawn from a point that can be resolved into 3 units across and 4 units up; algebraically it has a magnitude or value(length of the line) that is given by \[\sqrt{a^2 +b^2}\] which is in this case [\sqrt{3^2 +4^2}\] = 5 as a further note on geometry, imagine a straight line of length 5 units that is put at some angle on the (x,y) plane such that from its start to its endpoint is 3 units in the x direction but 4 units in the y direction

Best ResponseYou've already chosen the best response.0this one is just like the others just that another variable (z) was introducednot that 'z' was not present in the previous ones but the 'z' values there were 0... such as you show now are known as 3D vectors...

Best ResponseYou've already chosen the best response.0a drawing is another way of describing the vector geometrically...but for a vector: [a] [b] [c], where a,b and c are values...it says that you are moving 'a' units along the xaxis, then 'b' units along the yaxis, and finally 'c' units along the zaxis...do you understand? algebraically it is the length of the resultant vector from moving from your original point to the final point: it is found by using this formula: \[\sqrt{a^{2} + b^{2} + c ^{2}}\] do you see the difference of this with the one b4?
