    Vector Problem - Need Help

    Hi I'm new here I'm engineering student from NY.

    Question: Consider the planes vector u r = d1 and vector V r = d2, if vector u x v not equal to zero, give a vector which is tangent to the intersection of the planes

    Thanks

    I do not understand the wording used in this question.
    These two planes are not parallel so their intersection is a line.
    So it makes no sense to say a vector which is tangent to the intersection.
    Do you mean parallel instead of tangent?

    I got this question from a homework. I don't understand the question too.

    Then you need to asked the person who wrote the question what it means.
