Derivation of bessel generating function

• arunavdev
In summary, the Bessel generating function is a mathematical tool used to find solutions to differential equations involving Bessel functions. Its derivation involves simplifying the power series expansion of the exponential function and Bessel functions. This function is important in various fields of mathematics, including physics, engineering, and signal processing. However, it has limitations and is only applicable to linear differential equations. In practical applications, it is used to calculate vibrations, analyze heat transfer, solve problems in quantum mechanics, and in image and pattern recognition and signal processing.

Homework Statement

The bessel generating function:
exp(x*(t-(1/t))/2)=sum from 0 to n(Jn(x)t^(n))

The Attempt at a Solution

exp(x*(t-(1/t))/2)=exp((x/2)*t)exp((x/2)*(1/t))
used the McLaurin expansion of exponentials. Not sure how to bring the powers equal to that of the right hand side.
How could I type symbols wthout using latex.

Thanx

To type symbols without using latex: Look at this https://www.physicsforums.com/blog.php?b=347" from Redbelly98.
