webworks 10.2

Hi professor Taylor,

     On the 10.2 Webworks question 3 and several other problems involving vectors will not take my answers because it says "your answer isn't a vector (it looks like a point)". So I was wondering how you input a vector into Webworks.

Thank you,

Basically the same way webwork gives you the vector:  as a tuple of numbers enclosed by sharp brackets, e.g.:  v=<1,2,3>.  You probably did the reasonable thing of giving it a tuple enclosed by round brackets (1,2,3), which would be fine for me, but webwork wants the other because of reasons. 

BTW,  in webwork at the bottom of each homework there is a button that says "Email instructor".  If you contact me using that button it will show me the page as you see it with your answers.
