I need a fast shotgun method to spit out the coordinates of both vectors, there has to be something out there that I don't know of!

Thanks in advance guys!

Let $\displaystyle A(x_a, y_a)$ and $\displaystyle B(x_b, y_b)$. Knowing that A+B+P=0 we can write 2 equations:

$\displaystyle x_a+x_b=0$

$\displaystyle y_a+y_b=19$

or

$\displaystyle |A|cos(a)+|B|cos(b)=0$

$\displaystyle |A|sin(a)+|B|sin(b)=19$

So, you can find lengths |A| and |B| and coordinates from this system. - Sep 30th 2009, 03:09 PMProvoke
