Final answer:
To find the area of one leaf of the three-leaved rose with polar equation r=4 cos(3\theta), integrate \(\frac{1}{2}(r(\theta))^2\) from 0 to \(\frac{\pi}{3}\) and express the result using \(\pi\) as needed.
Step-by-step explanation:
The student's question pertains to finding the area of one leaf of the three-leaved rose represented by the polar equation r=4 cos(3\theta). To compute the area of one leaf of the rose, we need to use the formula for the area in polar coordinates, which is \(A = \frac{1}{2} \int (r(\theta))^2 d\theta\). The three-leaved rose will complete one full leaf as \(\theta\) goes from 0 to \(\frac{\pi}{3}\), since the full rose has three leaves and symmetry over the interval \([0, 2\pi]\).
The area of one leaf can be calculated as follows:
- Set up the integral: A = \frac{1}{2}\int_0^{\frac{\pi}{3}} (4 \cos(3\theta))^2 d\theta.
- Compute the integral using trigonometric identities and integration techniques.
- Simplify the result to get the area in terms of \(\pi\).
The exact computation would involve evaluating the definite integral of the squared polar equation within the specified limits.
