\frac{d}{d x} (x - arctan (x))

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

Solution steps

\frac{d}{d x} (x - arctan (x))

Apply the Sum/Difference Rule:

(f \pm g)^{'} = f^{'} \pm g^{'}

= \frac{d x}{d x} - \frac{d}{d x} (arctan (x))

\frac{d x}{d x} = 1

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

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

\frac{\partial}{\partial x} (ln (x^{2} + y))

\int \frac{2 + u}{u} d u

y = x^{3} (3 - x^{2})

\frac{\partial}{\partial x} (sin (π (4 x - 2 y)))

y = 3 x^{2}, at x = 1
