I got the same answer but my teacher marked it as only half right. She said you have to continue?


Michael J.

I don't know why your teacher said you have to continue.  -√(3)/2 is the most simplest solution to this.


Andrew M.

I agree with Michael.  The only possible other thing you could do at that point would be to work it out to a decimal which is not necessary.  You really need to ask your teacher to explain the reasoning and show you what else he/she wants done.
