area 3sin(x),4cos(x),[0,0.8pi]

area

3 sin (x), 4 cos (x), [0, 0.8 π]

7.07590 \dots

Solution steps

Apply the area formula:

\int_{0}^{0.8 π} ∣ 3 sin (x) - 4 cos (x) ∣ d x

Solve

\int_{0}^{0.8 π} ∣ 3 sin (x) - 4 cos (x) ∣ d x : 7.07590 \dots

The area is:

= 7.07590 \dots

\frac{d}{d x} (- 4 sec^{2} (x) + 6 sec^{4} (x))

x \to 3 lim (- 3 x - 7)

e^{u}

\int cos^{10} (x) d x

\int \frac{4 x - 1}{x ^{2} + 2 x + 5} d x
