Just doing some revision, making sure I know how to answer all the questions found on my mock exam paper.
I'm a little lost, trying to work out whether my vector results I J K are positive or negative because I calculate it to be positive but having looked at my exam result sheet it's negative and I checked to see if the exam sheet result was orthogonal and it was, so I must be going wrong somewhere.
11i is read as -11i on my mock exam results, can someone tell me where I'm going wrong? Thanks!
