I'm sorry, I'm new to this and I really need to draw 2D vectors. But, I wasn't sure how to go about it...I only have limited Python knowledge and from the looks of it, this runs on Python. I have vector a's trajectory and vector b's trajectory as well... What commands do I put in? I also need to do vector addition...I'd be really grateful if someone could help me out. Thank you. :)

Maybe something like that ?

sage: a = vector([1, 2])
sage: b = vector([4, 3])
sage: plot(a, color='red')
sage: plot(a, color='red') + plot(b, color='blue') + plot(a + b, color='black')
