Hi,

You cannot use a table to stack matrices you use the "stack" function.

Cheers

I am currently working on MATHCAD 15. It applied the same steps, but the following message appears:

__ this value must be real__, how to set it, ( attached file ).

The reason for the error is that pre is a nested matrix. Its element #14 is not a scalar but a 15x1vector.

The reason for this is that p is nested, its element #2 is a 15x1 vector

The reason for this is that epsilon is nested, its element #2 is a 15x1 vector

Haven't traced any further back.

Hi,

This was subtle.

in your sheet epsilon[2 set the element 2 of epsilon to a 15,1 matrix

in attached sheet I have got around this and given more points on the curves.

Hi,

I am not sure how the equation for area handles the bottom of the diagram.

Hi,

You still need to set the real volumes not the numbers 1 to 17

Cheers
