I'm a new user and can't seem to figure out how to enter vectors to graph. I read the post below but I need more elaboration. I want to plot 3 Force vectors in 2D. These originate from the origin but I'd also like to know how to plot from any point. I need to know graphically, bear with me, how to enter the x-y components....the whole shootin' match. Thanks for any enlightenment you could share.
