Homework Statement
x(t) = 6cos(t)−cos(6t) y(t) = 6sin(t)−sin(6t) 0 <= t <= 2*pi
I need to find the area cm2 with Th Green.
I need to find the radius and the center coordinate
Homework Equations
The Attempt at a Solution
$ = integral
1/2* ( 2*pi$0 ((x)dy - (y)dx) dt )
1/2 (2*pi$0 ((6cos(t)−cos(6t)*6cos(t)−6cos(6t) - (6sin(t)−sin(6t)*6sin(t)−6*sin(6t)) dt)
= 42*pi
How do I find the center? is it (0,0)?
