This function returns the first order Bessel function of the second kind and has the following form:
Y1(x)
The formula for the equation is:
/math-d1ee25cb77fed55ca9f40e58814d12ba.png "Y_1(x)=\lim_{v \rightarrow 1} Y_1(v, 1)")
where
/math-70da67d8ccb71cc1268ad40c50694989.png "Y_1(v,1)=\frac{J_{1}(x,v)\cos(v\pi)-J_{1}(x,-v)}{sin(v\pi)}")
Syntax
double y1(double x)
Parameter
x
- the input parameter.
Return
Returns the first order Bessel function of second kind at x.
Example
aa = y1(5); aa = ; //0.14786314339123
