Simplificar

x - 1 0^{\circ}

en una fracción:

\frac{18 x - 18 0 ^{\circ}}{18}

x - 1 0^{\circ}

Convertir a fracción:

x = \frac{x 18}{18}

= \frac{x \cdot 18}{18} - 1 0^{\circ}

Ya que los denominadores son iguales, combinar las fracciones:

\frac{a}{c} \pm \frac{b}{c} = \frac{a \pm b}{c}

= \frac{x \cdot 18 - 18 0 ^{\circ}}{18}

= tan (\frac{18 x - 18 0 ^{\circ}}{18}) cot (- x + 2 0^{\circ})
