derivative of

- \frac{7 x}{y}

- \frac{7}{y}

Solution steps

\frac{d}{d x} (- \frac{7 x}{y})

Treat

y

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

= - \frac{7}{y} \frac{d x}{d x}

Apply the common derivative:

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

= - \frac{7}{y} \cdot 1

Simplify

= - \frac{7}{y}

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

\int (\frac{k}{2018}) x^{2} d x

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

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

\int \frac{1}{8 x + 2 x ^{2}} d x
