    Find the reflection v' of v=i-3j+2k around the line i-k

    how can I do that? I am extremely rusty with math these days;

    Call i-k = W. I would calculate the vector projection of V on W, call it Vp. Then the reflected vector is 2Vp-V. Draw a little triangle/parallelogram and you will see it.
