Need help with this problem, I can understand how exactly to work it, could someone help?
The first thing to do is write those equations out in an orderly fashion as a set of linear equations in the F's and convert that into matrix form. Have you done that? What do you get?Quote:

Now rewrite this as a matrix equation.

Write it out so its in the form.
will be a 9x9 matrix. The first row might occurding to your first equation would be
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?
F=A\[0,0,1000,0,500,0,4000,-1105.14,0]'Quote:
