Answer 1

Answer:

$dy = \frac{ \frac{1.(x + 1) - 1.(x - 1)}{(x + 1) {}^{2} } }{2 \sqrt{ \frac{x - 1}{x+ 1} } } . \: dx \\ \\ dy = \frac{ \frac{x + 1 - x + 1}{(x + 1) {}^{2} } }{2 \sqrt{ \frac{x - 1}{x + 1} } } . \: dx \\ \\ dy = \frac{ \frac{2}{(x + 1) {}^{2} } }{2 \sqrt{ \frac{x - 1}{x + 1} } } . \: dx\\ \\ dy = \frac{ \cancel2}{ \cancel2 \: . \: (x + 1) {}^{2} \: . \: \sqrt{ \frac{x - 1}{x + 1} } } \\ \\ \boxed{ \bf dy = \frac{1}{(x + 1) {}^{2} \:. \: \sqrt{ \frac{x - 1}{x + 1} } } \: .\: dx}$
