# Integrals and area

### Integrals and area

Hello!

I am struggling with one homework excersise, could someone help me?
$$\begin{cases} x=3(t-sint) \\ y=3(1-cost) \end{cases}$$
$$y\ge 4,5$$ and $$0>x>2 \pi 3$$

as far as i know i can make this equation, but math teacher said that there are still some problems with the excersise
$$S= \int\limits_{0}^{2\pi3} 3(t-sint)3(1-cost)dt$$ or just replace $$2\pi3$$ with $$6\pi$$

Well, what, exactly, is the problem? Please go back and read it again! Is it possible that your "$$3\pi 2$$" is actually $$3\pi/2$$? And what are you to do with x and y? What you have written appears to be $$\int xy dt$$ which would be very peculiar.
