Hi. In my book about mathcad i have a formula (upper image), and i was try write this formula in mathcad (lower image). But result does not match. Maybe i lose some arguments?
Solved! Go to Solution.
Hi,
the value in brackets when "i" = 1 is 0. Multiply anything including a large number of products is zero.
set the limits of the product from i=2 to n.
Cheers Terry

Hi,
The produttoria must start from 2 to get as a result 1/2
Oh. Thanks! Maybe this book hame misspellings 🙂

Obviously it has 😉
In Mathcad or Prime you can also use a shorter (but mathematical somewhat sloppy) notation:
Makes me wonder: which is your 'book about Mathcad'? (Title, author...)
Luc
original book maybe not have misspelling.
I am reading the book in pdf format what have scan errors 🙂
From 0 to 1/2 or from 2 to 1 is too different to be a 'scan error'....
Again: what's the book?

A few lines above you see that its meant starting with i=2:
To get this (appearance of) symbolic output in Mathcad they must have done some work:
either define the value of 2 to a variable the name of which appears to be 1, or
it was a picture cut and paste.

Exactly right! Involves a key combination not available in Prime:
There should be a way to pull this trick in communication with my bank. Imagine how I then could easily double the deposits, or halve the withdrawals.

I don't think that what we see in the pdf is a real screenshot of a Mathcad expression. Rather it was typeset in the printing house and the typesetter made a mistake.
Yes, I know that a look alike can be done in Mathcad, but I was talking about the pdf of that book. If I look at the typeface used, the size of the product character Pi in relation to the other characters I don't think that we see a screen shot here and guess it was rather typeset (with an error).
BTW, we could also fake that in Prime, too:
That result should be undetermined, rather than 1/2.

We are just playing around to reproduce the typo in the russian pdf and other similar nonsense using Mathcad or prime tricks which Valery would like 😉
