Hi, was wondering how I would display or plot vectors with I, j and k components. Can do it when there is only I and j (2 components-just x and y axis). I know there is a x,y and z plane but don't know how to actually plot it, for example:

sketch the parallelogram with position vectors A(I+2j-K), B(2i+j-2k) and C(4i-k). I don't know how to get represent the 3rd point so as to see what I'm supposed to be looking at to do other calculations.

Well, if you want an actual plotting, you would have to plot the points in all the three dimensions. But since you only have paper, you will have to draw it in 2 dimensions, although that will not seem as real.

For my part, I do such sketches in 2D. That is, I draw a basic parallelogram, name the vertices A, B, C and D with the given data, ignoring the actual positions of the points in reality. I use vectors to find the coordinates of the last point, D.

Use the drawing provided to find the point D, that you need to form the parallelogram

Is that a bug you have in your picture galactus? :confused:

I think I will delete that. It isn't a very good representation. It shows the planes instead of the vectors. Sorry about that.
