Question

What function is this?

I'm using MathCAD14 and I am working with a xmcd sheet I pulled from this site, Truss2D.xmcd. With in this sheet is a plot for the elements defined. The plot uses the functions Im(Sind), Im(Fg), & Im(Vg), see attached. I believe the Im is the imaginary function. However, Sind, Fg, & Vg are not defined any where else in the sheet and I'm unable to locate these in the help file. Can anyone provide some insight on these functions?

Re() and Im() are functions which give you the real / imaginary part of their arguments

Sind, Fg and Vg are not Mathcad functions but variables and they sure have to be defined in the sheet somewhere. Telling from the plot Sind for example seems to be a vector consisting of four imaginary scalars - the real parts of those are the absicissa and the imaginary part represent the ordinate value of the four points we see in the plot.

Simply click in an empty space in te sheet and type Sind= and click outside the region or press enter. You should see that vector.

Werner,

I have reviewed the Sind, Fg, and Vg functions. They are matrices with imagnary and real numbers corresponding to the input matrix I created. Sind, Fg, and Vg are not defined anywhere else in the sheet. Do you have any other thoughts? Have you reviewed the original sheet I worked from (Truss2D.xmcd)?

Found Sind, Fg, & Vg in a hidden region previously un opened.
