the problem goes:(adsbygoogle = window.adsbygoogle || []).push({});

ABCD is a parallelogram in which points P and Q are the midpoints of sides BC and CD, respectively. Use vector calculus to prove that AP and AQ trisect the diagonal BD at the points E and F.

.....A _________B

....../......F...../

..../...E......../P

D/________/C

........Q

(Imagine lines from D->B, A->Q and A->P, where AQ passes through E and AP passes through F)

I set the Problem Up like this:

DE= x(DA+AB)

EF= y(DA+AB)

FB= z(DA+AB)

After this I get stuck running around in circles trying to make subsitutions to show that x, y & z = 1/3.

Ideas anyone?
