derivative of

cos (3 t)

- sin (3 t) \cdot 3

Solution steps

\frac{d}{d t} (cos (3 t))

Apply the chain rule:

- sin (3 t) \frac{d}{d t} (3 t)

= - sin (3 t) \frac{d}{d t} (3 t)

\frac{d}{d t} (3 t) = 3

= - sin (3 t) \cdot 3

\frac{d}{d x} (\frac{10 x}{( x ^{2} + 1 ) ^{2}})

\frac{d y}{d t} = (t + y)^{2} - 1

x \to 5 lim (9 - x^{2})

\int \frac{y}{y + 3} d y

x \to 0 lim (\frac{5 x ^{2}}{x ^{4}})
