Integral of cos(ln(x)) dx: A Third Method Via Euler's Identity

Ramanujan's Beautiful Master Formula: Integral From 0 to ∞ (e)^(-x^n)sin(x^n) dx
\begin{align*} & f(x)=\sum_{n=0}^{\infty} \phi(n) \dfrac{(-x)^n}{n!} \LongrightarrowM \left[ f(s) \right] = \int_0^{\infty} x^{s-1}f(x) dx = \Gamma(s) \phi(-s) \\& \\& \therefore \int_0^ {\infty} e^{{-x}^n} \sin (x^n) dx = \dfrac{\left( \dfrac{1}{n} \right)! \sin

Integral from 0 to 1 (ln(1/x))^b dx
\begin{align*} & \int_0^1 \ln^b{(x)} dx = (-1)^b (b)! \\& \\& {\rm{Proof}}: \\& \\& \therefore x=e^u \Longrightarrow \int_{-\infty}^0 u^b e^u du \\& \\& \therefore u=-g \Longrightarrow (-1)^b \int_0^{\infty} g^b e^{-g} dg
Integral from 0 to 1 ln(x)ln(1-x) dx
BPRP achieved this result using power series. Today I will solve it using the Bose Integral. \begin{align*}& \int_0^1 \ln{(x)}\ln{(1-x)} dx = 2 - \dfrac{\pi^2}{6} \\& \\& {\rm{Proof}}: \\& \\& \therefore
Integral from 0 to ∞ [x^a/(x^b+1)] dx
\begin{align*}& I(a, b) = \int_0^\infty \dfrac{x^a}{x^b+1} dx =\dfrac{\beta(\dfrac{a+1}{b}, 1-\dfrac{a+1}{b})}{b} \\& \\& {\rm{Proof}}: \\& \\& \therefore u=x^b \Longrightarrow \int_0^\infty \dfrac{u^{\frac{a-b+1}{b}}}{b(u+1)} du \\& \\& \therefore \int_0^\infty \dfrac{u^{\frac{a-b+1}{b}}}{b(u+1)} du = \dfrac{\beta(\dfrac{a+1}{b}, 1-\dfrac{a+1}{b})}{b} \\&
Feynman's Trick: Integral from 0 to ∞ [(e^(-x)-e^(-bx))/x] dx
\begin{align*}& I(b) = \int_0^\infty \dfrac{e^{-x}-e^{-bx}}{x} dx = \ln{(b)}\\& \\& {\rm{Proof}}: \\& \\& I'(b) = \int_0^\infty e^{-bx} dx = \dfrac{1}{b} \\& \\& \therefore I(b) = \ln{(b)} + C \\& \\& \therefore
Integral from 0 to 1 [ln(x)/(x-1)] dx
BPRP solved this integral using power series back in 2017. Today I will solve it using the Bose Integral. \begin{align*}& \int_0^1 \dfrac{\ln{(x)}}{x-1} dx = \dfrac{\pi^2}{6} \\& \\& Proof: \\& \\&
