derivative of

f (x) = x^{2} + 4

\frac{x}{x ^{2} + 4}

Solution steps

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

Apply the chain rule:

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

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

\frac{d}{d x} (x^{2} + 4) = 2 x

= \frac{1}{2 x ^{2} + 4} \cdot 2 x

Simplify

\frac{1}{2 x ^{2} + 4} \cdot 2 x : \frac{x}{x ^{2} + 4}

= \frac{x}{x ^{2} + 4}

\frac{d}{d x} (16 - 4 sin^{2} (7 π x))

\int_{- 1}^{0} \frac{1}{1 - x ^{2}} d x

f (x) = \frac{1}{2 x}, at x = 25

- \frac{6 x}{x ^{2} + 1}

\frac{d}{d x} (ln ((arcsin (x))^{2}))
