You CANNOT ignore the division by zero situation because mathematically it makes no sense to divide by zero.

Essentially you should catch this exception before it occurs. So next to checking if the ratio of Co and Cc is between -1 and 1, you should include a test that Co and Cc should not be equal.

Be sure to provide proper answer(s) for you program in case the exception(s) occur.

But maybe it's simpler to do just:

Change the second 'less than' into a 'less then or equal'.

 

 

Success!

Use please the try operator (on error in Mathcad 15)

Thank you

 

Actually I am expecting  this result . It happened only when I include  + 1 as I marked in yellow color

Ah, but 1 - Co/Cc + 1 = 2 - Co/Cc.

Then you don't have a problem when Co=Cc, but only when Co=2*Cc.
