The Excel Bessely function returns the Bessel function, Yn(x), (also known as the Weber function or the Neumann function), for a specified order and value of x.
The syntax of the function is:
where the function arguments are as follows:
|x||-||The value at which the function is to be evaluated.|
|n||-||n is a decimal, it is truncated to an integer by Excel).(If the supplied value of|
The above chart on the right shows the order 1 Bessel function, Yn(x).
If you want to calculate the value of this function at x = 0.05, this can be done using the formula:
which gives the result -12.78985516.
See the Microsoft Office website for further information on the Excel Bessely function.
If you get an error from the Excel Bessely function this is likely to be one of the following:
|#VALUE!||-||Occurs if any of the supplied arguments are non-numeric.|
