Definite integral

\begin{align} \int_{ 0 }^{ \pi } \cos \left(x\right) \,\mathrm{d}x&= \left[ \sin \left(x\right) \right]_{ 0 }^{ \pi }\\ &= 0-0 \\&= 0 \\& \approx 0.0 \end{align} Help to find the primitive function

Mean value

\begin{align} \mu&=\frac{1}{b-a}\int_{a}^{b}f(x)\,\mathrm{d}x\\&=\frac{ 0 }{ \pi }\\&= 0 \\&\approx 0.0 \end{align}
