I have a very simple formula to plot. But it says the formula is not valid.

The mathcad file is attached with the message.

Can anyone please check out and let me know whats the error.

Many thanks...

getneotome,

I think you left out the multiplication operator in your last term.

It looks like you typed (K^2+2*K(1-10(K))/11(K) ).


It should be (K^2+2*K*(1-10*K) / (11*K ).

(I've altered the () a little, but I guess you can follow that.

I typed it this waay and it works. klThe result is F(K) = a matrix 15 rows X 1 col.


Oh, and your 10 I think might be I0, if that is an I, you must define I with a value. Ditto for your 11 in the denominator, that looks like I0. I typed it in as 10 and 11.



Hope this helps.


regards,

I0 and I1 are Mathcad's built-in Bessel functions.

The only entry error is the missing multiplication of 2K and 1-I0(K) in the second numerator.
