# I hope there will be no convergence issues (eighteenth integral)

Calculus Level 5

$\displaystyle {\huge \int_{0}^{1} } \left( x + \dfrac{x}{x+ \dfrac{x}{x+\dfrac{x}{x+...}}} \right) \, dx$

If the above integral can be represented in the form

$\dfrac{a}{b} + \dfrac{c \sqrt{d}}{f} - g \ln \left( \dfrac{h + \sqrt{j}}{k}\right)$

where

• $$\gcd(a, b) = \gcd(c, f) = \gcd(h, k) = 1$$
• $$a, b, c, d, f, g, h, j, k$$ are all positive integers
• $$d, j$$ are square-free
• $$g = 2$$

then find $$a+b+c+d+f+g+h+j+k$$.

Bonus: What special number is contained somewhere in the answer to this problem?
