You mean like finding

f1=

f2=

... and so on? - Sep 20th 2009, 08:20 PMCaptainBlack
No I mean:

Now rewrite this as a matrix equation.

Write it out so its in the form $\displaystyle Ax = b$.

$\displaystyle A$ will be a 9x9 matrix. The first row might occurding to your first equation would be

$\displaystyle \left[ \begin{matrix}

\frac{1}{\sqrt{2}} & 1 & 0 & 0 & 0 & 0 & 0 & 0 & 0 \end{matrix} \right]$

Captain Black has beat me to it so I will not go any further (I am still very slow with Latex) (Nod)

Okay i got the matrix equation

A= [ cosd(45),1,0,0,0,0,0,0,0; -cosd(45),0,0,1,cosd(48.81),0,0,0,0; -sind(45),0,-1,0,-sind(48.81),0,0,0,0; 0,0,0,-1,0,0,0,cosd(48.81),0; 0,0,0,0,0,0,-1,-sind(48.81),0; 0,0,0,0,-cosd(48.81),1,0,0,1; 0,0,0,0,sind(48.81),0,1,0,0; 0,0,0,0,0,0,0,sind(48.81),0; 0,0,0,0,0,0,0,-cosd(48.81),-1 ]

Now where do I go from here? - Sep 20th 2009, 09:57 PMCaptainBlack
