area 15cos(x),15sin(x),[0, pi/2 ]

area

15 cos (x), 15 sin (x), [0, \frac{π}{2}]

302 - 30

Decimal Notation

12.42640 \dots

Solution steps

Apply the area formula:

\int_{0}^{\frac{π}{2}} ∣ 15 cos (x) - 15 sin (x) ∣ d x

Solve

\int_{0}^{\frac{π}{2}} ∣ 15 cos (x) - 15 sin (x) ∣ d x : 302 - 30

The area is:

= 302 - 30

\int sin (2 x) cos (5 x) d x

x + 3, \frac{( x + 3 )}{2}, - 3, 1

\frac{d}{d x} (4 x \cdot sin (x))

\int - sin (3 x) d x

n = 0 \sum \infty \frac{t ^{n}}{n !}
