(D) Given $	an A - 	an B = x$ and $\cot B - \cot A = y.$First,simplify $y$:$y = \frac{1}{	an B} - \frac{1}{	an A} = \frac{	an A - 	an B}{	an A 	an B} = \frac{x}{	an A 	an B}.$Therefore,$	an A 	an B = \frac{x}{y}.$Now,use the formula for $\cot(A - B)$:$\cot(A - B) = \frac{1 + 	an A 	an B}{	an A - 	an B}.$Substitute the values of $x$ and $	an A 	an B$:$\cot(A - B) = \frac{1 + \frac{x}{y}}{x} = \frac{1}{x} + \frac{x}{xy} = \frac{1}{x} + \frac{1}{y}.$

If $\tan A - \tan B = x$ and $\cot B - \cot A = y,$ then $\cot (A - B) = $
