    Please see the attached work.

    My final answer places the resultant vector in quadrant 4 (+ real, - imag) but pictorially when I add the two you can see I should be in the first quadrant... what's wrong?

    Thanks

    When you add the two rectangular components of f(x) and g(x) you should get,

    11.4 + j4.57 not 11.4 - j4.57

    No need to be embarassed, just be happy you have the correct understanding of the ideas/concepts. (From what I can tell atleast)

    Algebra mistakes are trivial, we all make them at somepoint or another.
