\frac{d}{d y} (arcsin (x - y))

- \frac{1}{1 - x ^{2} + 2 x y - y ^{2}}

Solution steps

\frac{d}{d y} (arcsin (x - y))

Treat

x

as a constant

Apply the chain rule:

\frac{1}{1 - ( x - y ) ^{2}} \frac{d}{d y} (x - y)

= \frac{1}{1 - ( x - y ) ^{2}} \frac{d}{d y} (x - y)

\frac{d}{d y} (x - y) = - 1

= \frac{1}{1 - ( x - y ) ^{2}} (- 1)

Simplify

\frac{1}{1 - ( x - y ) ^{2}} (- 1) : - \frac{1}{1 - x ^{2} + 2 x y - y ^{2}}

= - \frac{1}{1 - x ^{2} + 2 x y - y ^{2}}
