\frac{d}{d x} (x^{4} \cdot sin (x) \cdot sin (3 x))

4 x^{3} sin (x) sin (3 x) + (cos (x) sin (3 x) + cos (3 x) \cdot 3 sin (x)) x^{4}

Solution steps

\frac{d}{d x} (x^{4} sin (x) sin (3 x))

Apply the Product Rule:

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

f = x^{4}, g = sin (x) sin (3 x)

= \frac{d}{d x} (x^{4}) sin (x) sin (3 x) + \frac{d}{d x} (sin (x) sin (3 x)) x^{4}

\frac{d}{d x} (x^{4}) = 4 x^{3}

\frac{d}{d x} (sin (x) sin (3 x)) = cos (x) sin (3 x) + cos (3 x) \cdot 3 sin (x)

= 4 x^{3} sin (x) sin (3 x) + (cos (x) sin (3 x) + cos (3 x) \cdot 3 sin (x)) x^{4}

\frac{\partial}{\partial t} (s^{2} + t^{2})

\int \frac{10}{( 20 x + 1 ) ^{23}} d x

\int 6 csc (x) cot (x) d x

\frac{\partial}{\partial x} (e^{7 y^{2}} + 9)

y^{^{''}} - y = (2 - 4 x) e^{- x} + 10 cos (2 x)
