vector input

i feel like wolfram alpha should plot vectors by typing vector ai+bj where a and b can be variables or constants or a product of both

Since you kind of need it soon, can you make do with modifications to this
http://www.wolframalpha.com/input/?i=plot+%7B%7B0%2C0%7D%2C%7B3%2C4%7D%7D
or this

(notice how I inserted an extra {0,0} to get back to the origin so I could then plot another vector from the origin to a second point)

WolframAlpha doesn't seem to let me use variables when plotting vectors, but perhaps you can get by with constants to get your work done and turned in.

I passed on the suggestion to the Wolfram|Alpha developers.  Thank you.

(It is not a trivial change.  Don't expect it soon.)

Suggestions for Wolfram|Alpha can be sent through the feedback window at the bottom of
the wolframalpha.com page.  (The little slot opens wider when you type in it.)
