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

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

Solution steps

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

Apply the chain rule:

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

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

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

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

Simplify

\frac{1}{2 1 + x ^{2}} \cdot 2 x : \frac{x}{1 + x ^{2}}

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

\int x 9^{x} d x

\int \frac{1}{26 - x ^{2}} d x

\frac{d}{d x} (\frac{4 x + 2}{x + 1})

\int tan^{5} (5 x) d x

\int \frac{e}{x} + \frac{x}{e} d x
