$\int (t^{2} + t) \cos (3 t) d t$

Step 1

Apply the distributive property.

$\frac{d}{d x} [\int t^{2} \cos (3 t) + t \cos (3 t) d t]$

Step 2

Since $\int t^{2} \cos (3 t) + t \cos (3 t) d t$ is constant with respect to $x$ , the derivative of $\int t^{2} \cos (3 t) + t \cos (3 t) d t$ with respect to $x$ is $0$ .

$0$
