*The Bessel function of the first kind of order can be expressed as:

*The Bessel function of the first kind of order can be expressed as:

<math>Jn(x)=\sum_{k=0}^\infty \frac{(-1)^k}{k!\Gamma(n+k+1)}.(\frac{x}{2})^{n+2k}</math>

<math>Jn(x)=\sum_{k=0}^\infty \frac{(-1)^k}{k!\Gamma(n+k+1)}.(\frac{x}{2})^{n+2k}</math>

*where <math>\Gamma(n+k+1)=(n+k)!<math> or   

*where <math>\Gamma(n+k+1)=(n+k)!</math> or   

*\int\limits_{0}^{\infty} x^{n+k}*e^{-x} dx is the gamma function.

*<math>\int\limits_{0}^{\infty} x^{n+k}*e^{-x} dx</math> is the Gamma Function.

*This function will give result as error when  

*This function will give result as error when  

  1. <math>x</math> or <math>n</math> is non numeric

  1. <math>x</math> or <math>n</math> is non numeric

  2. <math>n<0</math>, because <math>n</math> is the order of the function

  2. <math>n < 0</math>, because <math>n</math> is the order of the function
