3.4.69 \(\int \frac {x}{\text {arcsinh}(\sinh (x))} \, dx\) [369]

3.4.69.1 Optimal result

Integrand size = 7, antiderivative size = 27 \[ \int \frac {x}{\text {arcsinh}(\sinh (x))} \, dx=\text {arcsinh}(\sinh (x))+\log (\text {arcsinh}(\sinh (x))) \left (-\text {arcsinh}(\sinh (x))+x \sqrt {\cosh ^2(x)} \text {sech}(x)\right ) \]

output

arcsinh(sinh(x))+ln(arcsinh(sinh(x)))*(-arcsinh(sinh(x))+x*sech(x)*(cosh(x 
)^2)^(1/2))
 

3.4.69.2 Mathematica [B] (warning: unable to verify)

Leaf count is larger than twice the leaf count of optimal. \(148\) vs. \(2(27)=54\).

Time = 0.22 (sec) , antiderivative size = 148, normalized size of antiderivative = 5.48 \[ \int \frac {x}{\text {arcsinh}(\sinh (x))} \, dx=-\log \left (\frac {1}{2} e^{-x} \left (-1+e^{2 x}+e^x \sqrt {2+e^{-2 x}+e^{2 x}}\right )\right ) \left (-1+\log \left (\log \left (\frac {1}{2} e^{-x} \left (-1+e^{2 x}+e^x \sqrt {2+e^{-2 x}+e^{2 x}}\right )\right )\right )\right )+\frac {e^x \sqrt {2+e^{-2 x}+e^{2 x}} x \log \left (\log \left (\frac {1}{2} e^{-x} \left (-1+e^{2 x}+e^x \sqrt {2+e^{-2 x}+e^{2 x}}\right )\right )\right )}{1+e^{2 x}} \]
