[RESOLVED] [2005] Simple Equation that returns error

[surya]

Hi,
The eqn below is returning error with K =-1.#IND


k = arc cosine(-(g/2i)
which I coded as

   
k = Acos(-(g / 2 * i))

where
g=4.0740740740740744
i=8.3356375415197839

Will appreciate any responses...

acos (according to docs) only accepts Cosine as a value.
so it needs a value passed to it in the range of -1 to 1.
your number you are passing it is much smaller than -1.

Hi Orwell,
Thanks for your inputs;
