Double Integral One Loop of the Rose

In summary, a double integral one loop of the rose is a mathematical concept used to calculate the area of a specific region created by a given equation, known as the rose curve. It differs from a regular double integral in that the region being integrated over is defined by a specific equation. The rose curve has been studied and used in mathematics for centuries, with applications in various fields. The calculation of a double integral one loop of the rose involves breaking down the region into smaller, rectangular areas and summing the individual areas together. It has real-world applications in fields such as engineering, physics, and economics.

Homework Statement



Use a double integral to find the area of one loop of the rose r = cos 3[itex]\theta[/itex]

Homework Equations





The Attempt at a Solution



This is a past test question. The only thing I got wrong was the set up while I got the rest of the mechanical steps right. I set up as

∫∫ (r*cos 3θ) dr dθ

which is not right. I thought it might either be

∫∫ (r*r) dr dθ

or

∫∫ (cos 3θ * cos 3θ) dr dθ
