area 5cos(7x),5-5cos(7x)

area

5 cos (7 x), 5 - 5 cos (7 x)

\frac{10 3}{7} + \frac{20 π}{21}

Decimal

5.46635 \dots

Solution steps

Apply the area formula:

\int_{\frac{π}{21}}^{\frac{5 π}{21}} ∣ 5 cos (7 x) - (5 - 5 cos (7 x)) ∣ d x

Solve

\int_{\frac{π}{21}}^{\frac{5 π}{21}} ∣ 5 cos (7 x) - (5 - 5 cos (7 x)) ∣ d x : \frac{10 3}{7} + \frac{20 π}{21}

The area is:

= \frac{10 3}{7} + \frac{20 π}{21}
