$\frac{t a n 63^{\circ} + c o t 23^{\circ}}{t a n 27^{\circ} + c o t 67^{\circ}} - t a n 63^{\circ} t a n 67^{\circ} = \frac{c o t 27^{\circ} + \frac{1}{t a n 23^{\circ}}}{\frac{1}{c o t 27^{\circ}} + t a n 23^{\circ}} - t a n 63^{\circ} t a n 67^{\circ} t a n 23^{\circ} c o t 27^{\circ} + 1 = \frac{t a n 23^{\circ}}{\frac{1 + c o t 27^{\circ} t a n 23^{\circ}}{c o t 27^{\circ}}} - t a n 63^{\circ} t a n 67^{\circ} = c o t 27^{\circ} c o t 23^{\circ} - c o t 27^{\circ} c o t 23^{\circ} = 0$
