Solution

Let space straight y equals tan to the power of negative 1 end exponent open parentheses fraction numerator 1 minus cos space straight x over denominator sin space straight x end fraction close parentheses equals tan to the power of negative 1 end exponent open square brackets fraction numerator 2 sin squared begin display style straight x over 2 end style over denominator 2 sin begin display style straight x over 2 end style cos begin display style straight x over 2 end style end fraction close square brackets space space space space space space space space equals tan to the power of negative 1 end exponent open square brackets fraction numerator sin begin display style straight x over 2 end style over denominator cos begin display style straight x over 2 end style end fraction close square brackets equals tan to the power of negative 1 end exponent open parentheses tan straight x over 2 close parentheses therefore space space straight y equals 1 half straight x space space space space space space rightwards double arrow space dy over dx equals 1 half
