    Find unknown vector X if these relations hold true

    OK that makes sense... but how would i express X dot (B x C) when i am formulating the projection? I'm trying to take X out... :/

    Find unknown vector X if these relations hold true

    isn't (b x c) = X?

    Find unknown vector X if these relations hold true

    OK that makes sense! so I'm guessing Q would be the projection of X onto c? However I'm stuck from here because i cannot express that projection in terms of correct variables (don't know A dot C)... am i wrong?

    Find unknown vector X if these relations hold true

    Homework Statement If an unknown vector X satisfies the relation X · b = β X × b = c express X in terms of β, b, and c. Homework Equations X · b = |X||b|cos(θ) X × b = |X||b|sin(θ) The Attempt at a Solution I don't know where to start... :( someone pls give me a hint
