area 7cos(7x),7-7cos(7x),[0, pi/7 ]

area

7 cos (7 x), 7 - 7 cos (7 x), [0, \frac{π}{7}]

- \frac{2 π}{3} + π + 23

Decimal

4.51129 \dots

Solution steps

Apply the area formula:

\int_{0}^{\frac{π}{7}} ∣ 7 cos (7 x) - (7 - 7 cos (7 x)) ∣ d x

Solve

\int_{0}^{\frac{π}{7}} ∣ 7 cos (7 x) - (7 - 7 cos (7 x)) ∣ d x : - \frac{2 π}{3} + π + 23

The area is:

= - \frac{2 π}{3} + π + 23
