derivative of

9 - t

- \frac{1}{2 9 - t}

Solution steps

\frac{d}{d t} (9 - t)

Apply the chain rule:

\frac{1}{2 9 - t} \frac{d}{d t} (9 - t)

= \frac{1}{2 9 - t} \frac{d}{d t} (9 - t)

\frac{d}{d t} (9 - t) = - 1

= \frac{1}{2 9 - t} (- 1)

Simplify

= - \frac{1}{2 9 - t}

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

n = 0 \sum \infty \frac{4}{5 ^{n - 1}}

x \to - 2 - lim (\frac{x}{x + 2})

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

x \to 64 lim (x^{\frac{2}{3}})
