Calculate the determinant of the matrix along with the solution values of the forces within the links over the range of A or C locations depending on your scenario. Plot the force of the BD link as a function of the matrix determinant. Interpret how the determinant function can help in predicting the outcome of a linear system of equations. Attatched is my code. and pics if you cannot access code. My value for BD is -441.67 lb and my determinant is -0.0070. Please help completely lost with this.

Some context: help with fixing my plot please

Attatched is the original problem. I already found all the link forces as well as the determinant of the matrix (M) that i used. Now i must "Plot the force of the BD link as a function of the matrix determinant" which is what i need help with. I determined BD is -441.67 lb and my determinant is -0.0070. Attatched is also the structure in which i examined and found the 12 different forces on. Not sure if this clears it up at all.
