\(\displaystyle \text{Li}_{2}\left(\frac{1}{2}\right) = \frac{\pi^2}{12} - \frac{1}{2} \log^2 (2) \)
ZaidAlyafey said:I found the following functional equation :
\(\displaystyle \text{Li}_2(x)+\text{Li}_{2}(1-x) = \frac{\pi^2}{6}- \ln(x)\cdot \ln(1-x) \)
Substituting x = 1/2 gives us the result , does anybody know how to prove this functional equation ?
ZaidAlyafey said:But that still unsatisfactory
mathbalarka said:I don't see what's unsatisfactory to you. Galactus' derivation is perfectly logical and satisfactory as it occurs to me. If you want another proof, then you might be interested in a proof of Abel's identity which is a further generalization of the reflection formula.
ZaidAlyafey said:Actually it is , but I posted this before seeing the derivation...

A dilogarithmic value, also known as the Spence's function, is a special mathematical function that is used to evaluate the integral of the logarithmic function.
A dilogarithmic value is typically expressed as Li2(x), where x is the input value.
Proving a dilogarithmic value is important in mathematics as it helps to establish the validity of certain mathematical theories and equations. It also allows for more accurate calculations and predictions in various fields, such as physics and engineering.
The proof of a dilogarithmic value involves using various mathematical techniques and identities, such as the Euler-Maclaurin formula and the Cauchy residue theorem.
Dilogarithmic values have various applications in mathematics, physics, and engineering. They are used in the calculation of complex integrals and in the study of certain physical phenomena, such as heat transfer and fluid dynamics. They also have applications in fields such as cryptography and signal processing.
