integral from 0 to pi/3 of sec(x)

\int_{0}^{\frac{π}{3}} sec (x) d x

ln (2 + 3)

Decimal

1.31695 \dots

Solution steps

\int_{0}^{\frac{π}{3}} sec (x) d x

Use the common integral:

\int sec (x) d x = ln ∣ tan (x) + sec (x) ∣

= [ln ∣ tan (x) + sec (x) ∣]_{0}^{\frac{π}{3}}

Compute the boundaries:

ln (2 + 3)

= ln (2 + 3)
