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

\frac{2 x ^{2} - 3 x x + 1 - x + 1 + 2}{2 ( x ^{2} - 1 ) ^{2}}

Solution steps

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

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

Simplify

\frac{( - 1 + \frac{1}{2 1 + x} ) ( x ^{2} - 1 ) - 2 x ( - x + 1 + x )}{( x ^{2} - 1 ) ^{2}} : \frac{2 x ^{2} - 3 x x + 1 - x + 1 + 2}{2 ( x ^{2} - 1 ) ^{2}}

= \frac{2 x ^{2} - 3 x x + 1 - x + 1 + 2}{2 ( x ^{2} - 1 ) ^{2}}

\int sin^{3} (x) cos^{18} (x) d x

\frac{d}{d x} (\frac{( x ^{3} + y ^{3} )}{( x ^{2} + y ^{2} )})

\frac{d}{d x} (\frac{x + 2}{2})

49 y^{^{''}} + 70 y^{^{'}} + 25 y = 0

\int 4 tan (3 x) d x
