\frac{d}{d t} (\frac{cos ( t )}{t})

\frac{- t sin ( t ) - cos ( t )}{t ^{2}}

Solution steps

\frac{d}{d t} (\frac{cos ( t )}{t})

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

= \frac{\frac{d}{d t} ( cos ( t ) ) t - \frac{d t}{d t} cos ( t )}{t ^{2}}

\frac{d}{d t} (cos (t)) = - sin (t)

\frac{d t}{d t} = 1

= \frac{( - sin ( t ) ) t - 1 \cdot cos ( t )}{t ^{2}}

Simplify

= \frac{- t sin ( t ) - cos ( t )}{t ^{2}}

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

\int (x - 4)^{3} d x

\frac{d}{d x} (\frac{tan ( x )}{e ^{x}})

x \to - 1 lim (\frac{x + 4}{2 x + 1})

x \to 0 lim (\frac{∣ x ∣ - x}{x})
