Question

Is this a mistake in example 3? My answer is 1/sqrt(6), different to the one present here: http://ocw.mit.edu/courses/mathematics/18-02sc-multivariable-calculus-fall-2010/1.-vectors-and-matrices/part-b-matrices-and-systems-of-equations/session-12-equations-of-planes-ii/MIT18_02SC_notes_6.pdf

Answer 1

yeah, i got your answer and i did it a different way.

their mistake: the point Q they choose is NOT on the 2nd plane. use a correct value, they meant to use (3,0,0), and follow through and it works the way they show it

Answer 2
