derivative of

x^{2} + 9

\frac{x}{x ^{2} + 9}

Solution steps

\frac{d}{d x} (x^{2} + 9)

Apply the chain rule:

\frac{1}{2 x ^{2} + 9} \frac{d}{d x} (x^{2} + 9)

= \frac{1}{2 x ^{2} + 9} \frac{d}{d x} (x^{2} + 9)

\frac{d}{d x} (x^{2} + 9) = 2 x

= \frac{1}{2 x ^{2} + 9} \cdot 2 x

Simplify

\frac{1}{2 x ^{2} + 9} \cdot 2 x : \frac{x}{x ^{2} + 9}

= \frac{x}{x ^{2} + 9}

\int \frac{42}{1 - cos ( 6 x )} d x

\int (2 x y^{3}) d x

x \to 0 lim (\frac{x}{x ^{2} - x})

y^{^{'}} = e^{3 x + y}

\frac{d}{d x} (\frac{3 x ^{\frac{1}{2}}}{2})
