\frac{d}{d t} (e^{4 t} sin (t))

e^{4 t} \cdot 4 sin (t) + cos (t) e^{4 t}

Solution steps

\frac{d}{d t} (e^{4 t} sin (t))

Apply the Product Rule:

(f \cdot g)^{'} = f^{'} \cdot g + f \cdot g^{'}

f = e^{4 t}, g = sin (t)

= \frac{d}{d t} (e^{4 t}) sin (t) + \frac{d}{d t} (sin (t)) e^{4 t}

\frac{d}{d t} (e^{4 t}) = e^{4 t} \cdot 4

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

= e^{4 t} \cdot 4 sin (t) + cos (t) e^{4 t}

f (x) = 3 x^{2} - x^{3}

\int (9 + u + u^{2}) d u

\int \frac{4}{x ^{2} ( x - 2 )} d x

\int (x^{4} + x + 9) d x

x \to - 1 lim (3 x - 5)
