Find x/y + y/x, if log(x + y) + log(x - y) = 2log(x + y) - logx - logy - log2.
You asked:
Given \(\log\left( x + y \right) + \log\left( x - y \right) = 2 \cdot \log\left( x + y \right) - \log\left( x \right) - \log\left( y \right) - \log\left( 2 \right)\) evaluate the expression \(\frac{x}{y} + \frac{y}{x}\).
