I have two problems: 1. The problem statement, all variables and given/known data In general, what can be said about the vector product x×(x×y) 3. The attempt at a solution I thought the result of this would be parallel to y. However the answer suggests it is orthogonal to x. Can anyone explain how I could approach this question? I tried to visualize it in my head but it was very difficult. 1. The problem statement, all variables and given/known data Given two vectors of length 2 and 3 separated by an angle of 30 degrees, what is the cross product of the two vectors? 3. The attempt at a solution I know that the cross product = (length of vector a)*(length of vector b)*sin(theta) This gives us 3.0, however the answer key suggests there is not enough information to answer the question.
