derivative of

cos (2 t)

- sin (2 t) \cdot 2

Solution steps

\frac{d}{d t} (cos (2 t))

Apply the chain rule:

- sin (2 t) \frac{d}{d t} (2 t)

= - sin (2 t) \frac{d}{d t} (2 t)

\frac{d}{d t} (2 t) = 2

= - sin (2 t) \cdot 2

x \to - 3 lim (- x^{2} + 5 x - 1)

x \to + 0 lim (x^{2} cos (\frac{1}{x}))

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

\int_{0}^{4} \frac{6 t}{( t - 5 ) ^{2}} d t

\int (- 2 x^{5} - 5 x^{3} + 3 x^{2} + 1 - 4 e^{x}) d x
