integral from 0 to 1 of (11)/(1+p^2)

\int_{0}^{1} \frac{11}{1 + p ^{2}} d p

\frac{11 π}{4}

Decimal

8.63937 \dots

Solution steps

\int_{0}^{1} \frac{11}{1 + p ^{2}} d p

Take the constant out:

\int a \cdot f (x) d x = a \cdot \int f (x) d x

= 11 \cdot \int_{0}^{1} \frac{1}{1 + p ^{2}} d p

Use the common integral:

\int \frac{1}{1 + p ^{2}} d p = arctan (p)

= 11 [arctan (p)]_{0}^{1}

Compute the boundaries:

\frac{π}{4}

= 11 \cdot \frac{π}{4}

Simplify

= \frac{11 π}{4}
