I am trying to find the integral of:
where $a>2$, $R$ and $b$ are constant terms.
By using Wolfram Alpha, I found out that the function does not have an antiderivative. I have also tried to solve it using integration by parts but I am not able to find the integral of the denominator term.
Can anyone please guide me to a relevant resource where similar expressions have been integrated? Also, if you have any ideas on integrating such an expression, please feel free to share them.
